Answer: AWS CloudTrail

The correct answer is C. AWS CloudTrail. AWS CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. 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, and this can help you identify which IAM user made the specific changes to the security group rules during the production deployment.
