Socket Mode requires an app-level token carrying the `connections:write` scope. App-level tokens conventionally begin with `xapp-` and represent the application itself rather than a particular workspace bot installation. The application uses this credential with `apps.connections.open` to obtain the dynamically generated WebSocket URL required for Socket Mode communication. A bot token may still be necessary for subsequent Web API actions, such as posting messages, but a bot token alone does not establish the Socket Mode connection. Slack's current documentation explicitly identifies `connections:write` as supporting app-level tokens and being compatible with `apps.connections.open`. Legacy tokens are not the required credential, and Socket Mode certainly does not operate without authentication. Therefore, B is the only correct token type among the supplied options.

Slack officially provides Bolt framework implementations for Python, JavaScript, and Java. Bolt supplies higher-level abstractions for common Slack application functionality, including event listeners, interactive-component handling, OAuth-related patterns, API client access, acknowledgments, and middleware. Slack's platform documentation explicitly identifies Bolt for Python, Bolt for JavaScript, and Bolt for Java as the supported implementations. These frameworks use Slack's corresponding lower-level SDK capabilities underneath while presenting a more application-oriented programming model. Other languages can still interact with Slack because the Web API and Events API use standard HTTP-based mechanisms, and third-party libraries may exist for additional ecosystems. However, Ruby, Go, PHP, C++, Kotlin, and Swift are not the three officially maintained Bolt implementations specified by Slack. Therefore, A is the fully correct answer.

A is the current technically correct answer, replacing the uploaded bank's marked C. Slack's current token taxonomy does not define an “Admin” token type. Slack officially distinguishes token types such as bot tokens, user tokens, workflow tokens, and configuration tokens. Administrative authority is expressed through admin.* OAuth scopes attached to a user token, rather than through a separate token type called “Admin.” For example, Slack's official documentation for admin.conversations:read, admin.apps:read, and related Admin API scopes explicitly lists the supported token type as User. To obtain a user token imbued with Admin API scopes, the application must be installed at the entire Enterprise organization level by an authorized Org Admin or Org Owner. The resulting user access token can then call the applicable admin.* methods. Creating, inviting members to, and archiving channels require the appropriate administrative conversation scopes, particularly admin.conversations:*, subject to the installer having the corresponding Channel Management permissions. Therefore, under current Slack documentation, User is the correct token type. “Admin token” is outdated/imprecise terminology because admin describes the permission scope, not a distinct token class. This maps directly to APIs for Managing Your Slack.

Bolt provides a higher-level application framework that uses Slack's language SDKs underneath. Slack's platform overview explains that the Bolt frameworks for Python, JavaScript, and Java use the corresponding Slack SDKs to handle lower-level development details. The SDK layer exposes primitives such as Web API clients, authentication, HTTP requests, and API method implementations, while Bolt adds listener registration, middleware, context injection, interaction acknowledgment, event routing, and other application-development conveniences. This architecture allows developers to build Slack applications without repeatedly implementing platform plumbing themselves. Bolt and the SDKs therefore are not unrelated, nor do the SDKs automatically replace Bolt. Conversely, Bolt depends on the capabilities supplied by its underlying language ecosystem rather than functioning independently of them. Option B most accurately describes the documented architectural relationship between these components.

Slack's OAuth 2.0 authorization-code flow issues a temporary authorization code after the installing user reviews and approves the permissions requested by the application. Slack redirects the user to the application's configured redirect URI with this temporary code. The application backend then sends the code to Slack's token-exchange endpoint together with the required application credentials. If the exchange succeeds, Slack returns the applicable access credentials, which can include bot or user tokens depending on the requested authorization. Slack explicitly summarizes the process as requesting scopes, receiving user approval, and exchanging a temporary authorization code for an access token. A workspace ID identifies the Slack workspace but is not exchanged for credentials. Application manifests describe configuration, and user passwords must never be collected as part of Slack OAuth. Therefore, B is correct.

When a Bolt project is being developed locally through the current Slack CLI, `slack run` can watch application files and automatically restart the local application development server when supported source files change. Slack documents this behavior for Bolt for Python and Bolt for JavaScript projects. Python projects normally watch `.py` files, while JavaScript projects watch `.js` files unless the developer customizes the watch configuration. This live-reload capability shortens the development cycle because developers can modify application logic and have the running process restarted without manually stopping and relaunching it after every edit. The Slack workspace itself is not restarted, the user's browser is unaffected, and OAuth tokens are not regenerated merely because source code changes. Therefore, B is correct.

Under the current Block Kit specification, C is the technically valid answer, correcting the supplied key of A. A section block supports an accessory field containing one compatible Block Kit element. That accessory can be an overflow-menu element, and the overflow menu itself can contain multiple selectable options. Consequently, a section block containing an overflow menu can validly offer the user several choices while preserving a compact layout. Option A is structurally invalid as written because the accessory field is a single object, not an array of multiple button elements. When several independent buttons need to appear together, Slack's proper construct is an actions block, whose elements array can contain multiple buttons and other interactive elements. However, B incorrectly describes the actions block as a mechanism for displaying contextual images and text; its purpose is to hold interactive controls. A file block is unrelated to presenting user choices and D also incorrectly associates it with this decision-oriented use case. Therefore, based on current official Slack Block Kit definitions, C replaces the document's marked A answer. This belongs to Design the Interactive Flow of Your App, specifically selecting appropriate blocks and interactive elements.

Slack provides the app_uninstalled Events API event specifically to notify an application that it has been completely removed from a workspace. Current Slack documentation identifies this as an Events API-only event and states that no OAuth scope is required specifically to subscribe to it. The event payload identifies the application and workspace involved, allowing the application's backend to locate the corresponding installation information and execute cleanup operations. Typical cleanup responsibilities include removing stored installation tokens, workspace configuration, cached identifiers, and customer data that should no longer be retained after the installation relationship ends. Slack may also deliver tokens_revoked events when individual tokens are revoked. However, Slack explicitly notes that the ordering of tokens_revoked and app_uninstalled is not guaranteed. The definitive uninstall lifecycle signal in this question is therefore app_uninstalled. The remaining answer choices are not valid Slack event types for this purpose. Handling uninstall events is important for both application lifecycle management and data minimization. Applications should not indefinitely retain workspace data after the customer has terminated the integration unless a legitimate retention requirement applies. This maps to Design Your Workflows: Spotlight on Slack's APIs, specifically Events API lifecycle events and installation cleanup.

Public channels are the only conversation type among these choices for which Slack provides an explicit permission enabling an app to post without first becoming a member. The relevant permission is the chat:write.public scope, used together with chat:write. Slack describes chat:write.public as permitting a Slack app to send messages to public channels in which the application is not a member. Without that additional scope, an app normally must join the public channel or be invited before posting. Private channels require appropriate membership and authorization because allowing an app to post into a private conversation without membership would violate Slack's privacy model. Likewise, ordinary direct messages and multi-person direct messages have different membership and conversation-opening semantics and are not equivalent to posting freely into a public channel. The wording “by default” in the source is somewhat imprecise because granular-permission Slack apps do not automatically receive access to all public channels. They must request chat:write.public. Nevertheless, among the four conversation types, D represents the intended and technically supported capability. This question aligns with Design Your Workflows: Spotlight on Slack's APIs, particularly chat.postMessage, conversation membership, and OAuth scope behavior.

Slack apps can extend Workflow Builder by defining custom workflow steps. Slack describes workflow steps as functions added to an application that can subsequently be selected as steps by users creating workflows in Workflow Builder. Custom steps may be implemented through supported frameworks such as Bolt for Python, Bolt for JavaScript, Bolt for Java, or through Slack's Deno SDK. For Bolt applications, a custom step is defined and paired with a function listener that processes the corresponding execution request. This architecture allows organizations to expose specialized business logic—such as interacting with internal systems—as reusable automation components without requiring workflow creators to write code themselves. Workflow Builder is therefore not restricted to Slack's built-in actions, and using the Web API alone is not the only extension mechanism. Consequently, B accurately describes Slack's supported custom-step capability.
