Answer - A.
This is mentioned in the AWS Documentation.
AWS CloudFormation is a service that helps you model and set up your AWS resources using templates.
An AWS CloudFormation template is a text file whose format complies with the JSON standard.
You create a template that describes all of the AWS resources you want, and AWS CloudFormation takes care of provisioning and configuring those resources for you.
Option B is incorrect because Cloudwatch is a monitoring service and does not help to automate the deployment.
Option C is incorrect because Elastic Beanstalk cannot automate the deployment for the CodeDeploy service.
Option D is incorrect because AWS Config is not a service to automate the deployments.
For more information on using Cloudformation templates for CodeDeploy, please refer to the below URL-

The service that can help automate the deployment of the Code Deploy environment itself is AWS CloudFormation (Option A).
AWS CloudFormation is a service that allows you to create and manage AWS resources using templates. These templates are written in either YAML or JSON and define the infrastructure and resources needed for your application. CloudFormation automates the provisioning of resources and manages the entire lifecycle of those resources.
Using CloudFormation, you can create a template that includes all the resources needed for your Code Deploy environment, such as Amazon EC2 instances, Amazon S3 buckets, and IAM roles. Once the template is defined, you can use it to create and manage Code Deploy environments automatically, without any manual intervention.
AWS CloudWatch (Option B) is a monitoring and observability service that collects and analyzes metrics, logs, and events from AWS resources and applications. It can help you monitor the health and performance of your Code Deploy environment, but it cannot automate the deployment of the environment itself.
AWS Elastic Beanstalk (Option C) is a service that helps you deploy and manage web applications, but it is not specific to Code Deploy environments.
AWS Config (Option D) is a service that provides you with a detailed inventory of your AWS resources and their configurations, and also allows you to track changes to those resources over time. While it can help you monitor and manage the configuration of your Code Deploy environment, it does not provide the ability to automate the deployment of the environment itself.
Therefore, the correct answer is A. AWS CloudFormation.
