Answer: AWS CloudTrail

AWS CloudTrail is the correct answer. It provides a comprehensive audit trail of all API activity within your AWS account. It captures detailed information about API calls made to various AWS services, including the identity of the caller, the time of the call, the source IP address, the parameters passed, and the response received. This information helps you monitor and troubleshoot your AWS infrastructure, track changes made to resources, and investigate security incidents. The other options are incorrect because AWS Organizations is used for account management, AWS Config is for resource inventory, compliance, and configuration history, and Amazon CloudWatch is for monitoring AWS resources and applications.
