   A team is designing a CI/CD pipeline for an ML model that includes a source stage, a build stage, a test stage, and a deploy stage. They want to add a manual approval step before the deploy stage so that a data scientist can review the model metrics before production deployment. What is the recommended way to add this approval step in CodePipeline?

   • AAdd an approval action to the test stage after the test actions.
   • BUse a Lambda function in the test stage to pause the pipeline and wait for manual approval.
   • CAdd an approval action to the deploy stage before the deployment action.
   • DAdd a new stage between the test and deploy stages with an approval action.
