B is the correct answer.

This approach integrates directly into the existing AWS CDK deployment process. By writing a handler function within the CDK application, the developer can leverage the AWS SDK to programmatically identify and delete unused resources. The AWS CDK custom resource can then be used to invoke this function as part of the deployment process. This solution is efficient as it keeps everything within the CDK ecosystem and minimizes additional external configurations.

B. In the central AWS CDK application, write a handler function in the code that uses AWS SDK calls to check for and delete unused resources. Create an AWS CDK custom resource. Use the custom resource to attach the function code to an AWS Lambda function and to invoke the Lambda function when the deployment stack runs.

The correct answer is (B). Solution (B) is the best option because: Requires the LEAST amount of configuration: Solution (B) uses an AWS CDK custom resource, which is a type of resource that can be defined in AWS CDK code. Custom resources are a convenient way to add custom functionality to your AWS CloudFormation stacks. Integrates seamlessly into the current deployment process: Solution (B) uses the AWS CDK custom resource to attach function code to an AWS Lambda function and to invoke the Lambda function when the deployment stack runs. This means that the solution does not require any changes to the existing AWS CDK code.
