Application governance in an Enterprise Slack organization is performed through administrative roles rather than ordinary channel members or application developers. Slack currently allows Org Owners, Org Admins, and appropriate administrative roles to view and manage applications at the organization level. Organization administrators can approve or restrict applications and establish policies that affect workspaces throughout the organization. At the workspace level, Workspace Owners and designated app managers can review requests and manage applications within the authority allowed by organization-wide policies. Slack support does not perform routine customer app approvals, and the original application developer does not control whether another organization's administrators permit installation. Although current Slack role models are more granular than the wording of the question, option B correctly represents the responsible administrative groups.
