Answer: AWS CloudTrail

The correct answer is B, AWS CloudTrail. AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. By examining the CloudTrail logs, you can identify the last time a specific user accessed the AWS Management Console. The logs will provide information about console sign-in events, including the user, timestamp, and source IP address.
