Your client has a requirement of automatically signing users out of desktop and mobile instances...

The correct answer is D . The requirement is to automatically sign users out of desktop and mobile Slack sessions every 30 days. Slack session duration is a security control, so it belongs under org security settings rather than SSO settings. The duration is configured in hours, and 30 days equals 720 hours. Option A uses the correct security-settings area but expresses the duration as calendar days rather than the tested configuration value. Option B and Option C are incorrect because they place the control under SSO settings, but the requirement concerns Slack session duration for desktop and mobile instances, not SSO configuration itself. The consultant must translate the business requirement into the correct administrative setting and format: org-level security setting plus 720-hour session duration. This supports the client’s security posture by limiting persistent sessions and requiring periodic reauthentication across Slack clients.
