Slack's standard Bolt quickstart supports starter projects for Python and JavaScript. The Slack CLI workflow lets a developer create a sample application using Bolt for Python or Bolt for JavaScript and then run that project in a development workspace. Both frameworks provide higher-level abstractions for common Slack application patterns, including event listeners, interactive actions, Web API clients, acknowledgments, and context-aware utilities. Slack also maintains Bolt for Java as an official framework, but the particular starter-template choice described by the standard quickstart is Python or JavaScript. Ruby, Go, C#, PHP, Rust, and Swift are not the two out-of-the-box starter choices represented in this question. Therefore, B correctly identifies Python and JavaScript as the standard Bolt starter-template languages in the Slack CLI quickstart.

Block Kit Builder is Slack's visual prototyping environment for designing and previewing Block Kit layouts. It allows users to add, rearrange, and configure blocks while simultaneously reviewing the associated JSON representation and seeing how the completed layout will render. For the HR newsletter use case, the team can therefore construct and visually review a formatted message before the application or automation sends it to the required regional channel. Slack describes Block Kit Builder as a tool for choosing, configuring, arranging, and previewing blocks across Slack surfaces. Option A overstates its function: Block Kit Builder is not fundamentally a template-management repository for organizing recurring newsletters. Option C is also too broad. The builder can expose example interaction payloads and validate message composition, but it does not execute an application's complete backend interactivity workflow end-to-end. Option D is unsupported; it does not automatically convert arbitrary word-processing documents into production-ready Block Kit structures. Therefore, B accurately describes its intended role: prepare and preview the Slack UI/message composition before deployment. This belongs to Tools, specifically Block Kit Builder and visual prototyping of Slack application surfaces.

users.info provides the information required for both localization dimensions. Slack's user object contains timezone properties including tz, tz_label, and tz_offset. These values allow an application to schedule or render time-sensitive functionality according to the user's configured timezone rather than assuming the server's timezone or attempting to derive timezone information from HTTP headers. For language localization, users.info supports the include_locale=true parameter. When requested, Slack can include the user's locale, represented by an IETF language code. The app can then select translated strings and culturally appropriate presentation based on that locale. users.profile.get is intended for retrieving profile information and custom profile fields; it is not the preferred mechanism described by Slack for this combined localization requirement. HTTP request headers are also inappropriate for determining the Slack user's configured timezone because they represent network/request metadata rather than the user's Slack preference. Accordingly, D combines the appropriate API method with the two relevant user attributes. In implementation, the developer must remember to request locale explicitly using include_locale=true. This aligns with Design a Great User Experience, especially internationalization, localization, time-zone awareness, and tailoring application behavior to the individual Slack user.

Slack distinguishes between a development application installed only in its associated workspace and an application intended for installation across multiple workspaces. For a single-workspace application, Slack allows installation directly through the application's configuration without requiring the developer to implement a complete OAuth installation flow. Once an application is distributed to other workspaces, however, each installation must be explicitly authorized. Slack therefore requires the application to implement the OAuth 2.0 authorization-code flow and store the resulting installation information, including the applicable access tokens. OAuth is not required merely because an application has slash commands or a bot user. Those features require appropriate scopes and application configuration, but they do not independently dictate multi-workspace OAuth installation. OAuth is also not simply an optional additional security layer; it is Slack's authorization mechanism for obtaining workspace-specific authorization during distributed installation. The application typically sends the installer to Slack's authorization endpoint, receives a temporary authorization code through its configured redirect URI, exchanges that code through oauth.v2.access, and securely stores the resulting installation credentials. Therefore, C is correct and maps directly to Distribute Your App, particularly multi-workspace installation and OAuth-based authorization.
