Explanation:
Option B is the most efficient solution with the least operational overhead. By updating the existing API to include request validation and deploying it to a new API Gateway stage, the developer can test the changes without impacting the current production environment. Once the tests confirm the validation works as expected, the developer can then promote the updated API to the production stage. This approach minimizes operational overhead by avoiding the need to create or clone multiple APIs and stages.
