Answer: Snapshot and terminate the DB instance post-testing, then restore from the snapshot as needed.
The correct answer is C. Creating a snapshot of the DB instance when tests are completed, terminating the instance, and restoring from the snapshot when required is the most cost-effective solution. This approach ensures that the team incurs costs only when the DB instance is in use, while preserving the capacity and performance attributes needed for the tests. Options A, B, and D do not offer the same level of cost reduction, as they either involve keeping the instance running or scaling, which can still incur additional costs even if it's set to lower capacity.
