A Company Has Multiple Development Teams Sharing One AWS Account

A company has multiple development teams sharing one AWS account. The development team's manager wants to be able to automatically stop Amazon EC2 instances and receive notifications if resources are idle and not tagged as production resources. Which solution will meet these requirements?

A) Use a scheduled Amazon CloudWatch Events rule to filter for Amazon EC2 instance status checks and identify idle EC2 instances. Use the CloudWatch Events rule to target an AWS Lambda function to stop non-production instances and send notifications.
B) Use a scheduled Amazon CloudWatch Events rule to filter AWS Systems Manager events and identify idle EC2 instances and resources. Use the CloudWatch Events rule to target an AWS Lambda function to stop non-production instances and send notifications.
C) Use a scheduled Amazon CloudWatch Events rule to target a custom AWS Lambda function that runs AWS Trusted Advisor checks. Create a second CloudWatch Events rule to filter events from Trusted Advisor to trigger a Lambda function to stop idle non-production instances and send notifications.
D) Use a scheduled Amazon CloudWatch Events rule to target Amazon Inspector events for idle EC2 instances. Use the CloudWatch Events rule to target the AWS Lambda function to stop non-production instances and send notifications.
