Correct answer & explanation
✓
AWS CloudTrail
Options B and C are correct. AWS CloudTrail can be configured to record S3 data events, capturing API calls made to S3 buckets.

Option A (Amazon CloudWatch Logs) is used for monitoring and storing logs from various sources, but it does not natively generate S3 access logs. Option D (Amazon Macie) is for sensitive data discovery and classification. Option E (AWS Config) is for tracking resource configuration changes.
