The correct answer is D. Slack Connect approval behavior depends on the organization’s external collaboration settings, whether the external organization is already verified or trusted, and how the Enterprise Grid policies are configured. It is careless to tell a client that approval is always required or never required. In practice, approvals may be required depending on admin settings, workspace policies, external organization status, and whether the invitation is for a new or already approved relationship. Option A is wrong because Slack Connect approvals are not controlled by app approval settings; app governance and external collaboration governance are separate policy areas. Option B is too permissive and ignores enterprise controls. Option C is too absolute and ignores cases where admins configure more open collaboration rules. The consultant’s answer should be precise: approval is sometimes required, and the client should review Slack Connect settings during the Policies and Settings session so the external collaboration model matches their risk posture.
