A security engineer needs to build a solution to turn AWS CloudTrail back on in multiple AWS Regions in case it is ever turned off.
What is the MOST efficient way to implement this solution?

A. Use AWS Config with a managed rule to trigger the AWS-EnableCloudTrail remediation.
B. Create an Amazon EventBridge (Amazon CloudWatch Events) event with a cloudtrail.amazonaws.com event source and a StartLogging event name to trigger an AWS Lambda function to call the StartLogging API.
C. Create an Amazon CloudWatch alarm with a cloudtrail.amazonaws.com event source and a StopLogging event name to trigger an AWS Lambda function to call the StartLogging API.
D. Monitor AWS Trusted Advisor to ensure CloudTrail logging is enabled.
