A company runs an application on Amazon EC2 instances. The company uses a series of flaws CloudFormation stacks to define the application resources. A developer performs updates by building and testing the application on a laptop and then uploading the build output and CloudFormation stack templates to Amazon S3. The developer’s peers review the changes before the developer performs the CloudFormation stack update and installs a new version of the application onto the EC2 instances.
The deployment process is prone to errors and is time-consuming when the developer updates each EC2 instance with the new application. The company wants to automate as much of the application deployment process as possible while retaining a final manual approval step before the modification of the application or resources.
The company already has moved the source code for the application and the CloudFormation templates to flaws CodeCommit. The company also has created an flaws CodeBuild project to build and test the application.
Which combination of steps will meet the company's requirements? (Choose two.)

A. Create an application group and a deployment group in flaws CodeDeploy. Install the CodeDeploy agent on the EC2 instances.

B. Create an application revision and a deployment group in flaws CodeDeploy. Create an environment in CodeDeploy. Register the EC2 instances to the CodeDeploy environment.

C. Use flaws CodePipeline to invoke the CodeBuild job, run the CloudFormation update, and pause for a manual approval step. After approval, start the flaws CodeDeploy deployment.

D. Use flaws CodePipeline to invoke the CodeBuild job, create CloudFormation change sets for each of the application stacks, and pause for a manual approval step. After approval, run the CloudFormation change sets and start the flaws CodeDeploy deployment.

E. Use flaws CodePipeline to invoke the CodeBuild job, create CloudFormation change sets for each of the application stacks, and pause for a manual approval step. After approval, start the flaws CodeDeploy deployment.
