Selected Answer: A
option A leverages the AWS::CodeDeploy::BlueGreen transform hook in the CloudFormation template. This hook allows the developer to specify blue/green deployment strategies directly in the CloudFormation template. It facilitates deploying new versions to a subset of users (canary or linear deployments) before fully rolling out to all users. This approach is designed for seamless and automated deployments using AWS CodeDeploy and ECS.
