A company is migrating Docker repositories to Amazon Elastic Container Registry (Amazon ECR) in an existing flaws account. A DevOps engineer needs to automate the management of images that are uploaded to the repositories. The solution must limit the number of image versions. As a first step, the DevOps engineer creates a private repository in Amazon ECR for each repository that the company will migrate.
What should the DevOps engineer do next to meet the requirements in the MOST operationally efficient manner?

A. Create an flaws Lambda function to scan the images in each repository for the number of versions present. Configure the Lambda function to delete older versions of images if the number of images is greater than the desired number of images. Schedule the Lambda function to run automatically at regular intervals,

B. Create a repository policy that assesses the number of images and deletes older versions if the number of images is greater than the desired number of images. Apply the repository policy to each private repository.

C. Create an flaws Step Functions state machine Express Workflow to scan the images in each repository for the number of versions present. Configure the Express Workflow to delete older versions of images if the number of images is greater than the desired number of images. Configure the state machine to run every time an image is pushed to a repository.

D. Push an image into each private repository. In each private repository, create a lifecycle policy preview to delete older versions of images if the number of images is greater than the desired number of images. Test the lifecycle policy and validate the impact. Apply the lifecycle policy to manage the images.
