The uploaded UX Designer study guide identifies C. Determine the change in scope and impact of each enhancement request as the correct answer.

User acceptance testing has produced enhancement requests, but the next step should not be to implement them immediately. The study guide first requires the team to evaluate how each requested change affects the existing solution.

Assessing scope and impact allows the team to understand whether an enhancement is minor or substantial, what parts of the solution it could affect, and how it may change the originally planned work.

Option A moves directly into prioritization. Prioritization can be useful, but the guide's answer indicates that the requests first need to be understood in terms of their impact and scope before deciding how to implement them.

Option B suggests developing all requests in a sandbox. That assumes all requests should proceed to development, which is premature before their implications have been analyzed.

The testing principle represented here is controlled response to feedback. UAT findings may reveal valid improvements, but each change should be assessed systematically before implementation so that the team understands what the enhancement means for the overall solution.
