Correct answer & explanation
✓
AWS CloudTrail
(AWS CloudTrail). AWS CloudTrail logs all API calls made to AWS KMS, including key usage events, and retains event history for the past 90 days by default, making it suitable for auditing. Option A (VPC Flow Logs) captures network traffic, not API calls. Option C (AWS Config) tracks resource configuration changes, not API calls. Option D (Amazon Inspector) performs vulnerability assessments, not API logging.
