Answer: AWS CloudTrail

The correct answer is A, AWS CloudTrail. AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It provides a history of AWS API calls for your account, including calls from the AWS Management Console, AWS SDKs, command line tools, and higher-level AWS services. This service is essential for tracking user activity and API usage across your AWS infrastructure, allowing you to monitor and retain account activity related to actions performed in your AWS environment. The other options, such as Amazon Inspector, AWS WAF, and AWS Config, serve different purposes and do not provide the auditing capabilities that CloudTrail offers.
