Correct answer & explanation
✓
AWS CloudTrail
AWS CloudTrail records API calls made in an AWS account for auditing. Option A is wrong because VPC Flow Logs capture IP traffic information, not API calls. Option B is wrong because Amazon CloudWatch Logs is used to store and monitor log files, not to capture API activity. Option C is wrong because Amazon S3 server access logs record requests made to an S3 bucket, not all API calls across the account.
