A company uses Amazon RDS for all databases in its AWS accounts. The company uses AWS Control Tower to build a landing zone that has an audit and logging account. All databases must be encrypted at rest for compliance reasons. The company's security engineer needs to receive notification about any noncompliant databases that are in the company’s accounts.
Which solution will meet these requirements with the MOST operational efficiency?

A. Use AWS Control Tower to activate the optional detective control (guardrail) to determine whether the RDS storage is encrypted. Create an Amazon Simple Notification Service (Amazon SNS) topic in the company's audit account. Create an Amazon EventBridge rule to filter noncompliant events from the AWS Control Tower control (guardrail) to notify the SNS topic. Subscribe the security engineer's email address to the SNS topic.

B. Use AWS CloudFormation StackSets to deploy AWS Lambda functions to every account. Write the Lambda function code to determine whether the RDS storage is encrypted in the account the function is deployed to. Send the findings as an Amazon CloudWatch metric to the management account. Create an Amazon Simple Notification Service (Amazon SNS) topic. Create a CloudWatch alarm that notifies the SNS topic when metric thresholds are met. Subscribe the security engineer's email address to the SNS topic.

C. Create a custom AWS Config rule in every account to determine whether the RDS storage is encrypted. Create an Amazon Simple Notification Service (Amazon SNS) topic in the audit account. Create an Amazon EventBidge rule to filter noncompliant events from the AWS Control Tower control (guardrail) to notify the SNS topic. Subscribe the security engineer's email address to the SNS topic.

D. Launch an Amazon C2 instance. Run an hourly cron job by using the AWS CLI to determine whether the RDS storage is encrypted in each AWS account. Store the results in an RDS database. Notify the security engineer by sending email messages from the EC2 instance when noncompliance is detected
