You're a developer who has been asked to create a Slack app on the Business...

A Slack application created for use exclusively inside its associated workspace does not need public distribution or a multi-workspace OAuth installation architecture. Slack classifies such an application as an undistributed or single-workspace app. It can be installed directly into its associated development workspace through the app-management configuration. Because the IT manager needs access to the app's configuration, adding that person as an application collaborator provides the appropriate administrative access. The collaborator can then install the application to the Business Operations workspace through the app dashboard. Option A unnecessarily enables distribution to other workspaces. Once public distribution is activated, Slack provides a shareable installation URL intended for multi-workspace installations. Option C similarly introduces OAuth infrastructure that is required when distributing an application beyond its associated workspace but is unnecessary for this internal single-workspace scenario. Option D is even broader because Slack Marketplace publication is intended for externally distributed applications that have completed Slack's review process. Slack's current lifecycle documentation confirms that newly created apps reside in an associated workspace and can be installed there directly without building a separate authorization flow. This belongs to Distribute Your App, particularly understanding single-workspace versus distributed application models.
