Correct answer & explanation
✓
Amazon Athena
AWS CloudTrail captures API calls, Amazon S3 stores the logs, and Amazon Athena allows querying the logs. Alternatively, CloudWatch Logs can be used, but Athena is more cost-effective for ad-hoc analysis. The three correct services are CloudTrail, S3, and Athena.
