The correct answer is C. A delegated approver is the recommended Salesforce feature when the assigned approver is unavailable, such as during vacation. Salesforce documentation confirms that users can identify a delegate in approval settings, and delegated approvers can approve or reject approval requests.

This ensures the closed-won Opportunity can still be reviewed before the leaderboard is updated, even though the owner’s manager is away.

Why others are incorrect:

A is not the best recommended setup because relying on an assistant to reassign requests is manual and reactive.

B is incorrect because forwarding approval requests is not the standard solution for planned approver absence.

D is incorrect because assignment rules do not assign delegated approvers for approval processes.
