Correct answer: Backout plan.
Why this is the answer
A backout plan (also known as a rollback plan) details the steps to revert a system to its previous stable state if a change introduces problems. This is crucial for demonstrating that the system can be restored if a performance issue arises after a deployment. An impact analysis assesses the potential effects of a change but doesn't provide restoration steps. A test procedure verifies the functionality of the change but doesn't address reverting it. An approval procedure outlines the steps for gaining permission for a change, not for recovering from a failed one.
