Custom resources enable you to write custom provisioning logic in templates that AWS CloudFormation runs anytime you create, update (if you changed the custom resource), or delete stacks. For example, you might want to include resources that aren't available as AWS CloudFormation resource types. You can include those resources by using custom resources. That way you can still manage all your related resources in a single stack. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-custom-resources.html

Option D is correct. CustomType helps us to write the meaningful and logical nested stack template which the multiple AWS services consisted in 1 resource.

The Custom::MyCustomType is a CloudFormation custom resource type that allows you to define your own resource type using AWS Lambda-backed custom logic. This means you can use AWS Lambda functions to create and delete the custom resource. By creating a custom resource backed by an AWS Lambda function, you have the flexibility to define and orchestrate multiple AWS services as a single resource within your CloudFormation stack. The custom Lambda function can handle the logic for creating and deleting the resources across multiple services in the desired order and configuration.

Option A (AWS::EC2::Instance with a cfn-init helper script) is used to create an EC2 instance, but it does not provide the ability to create multiple AWS services as a single resource. cfn-init is useful for bootstrapping EC2 instances with additional configuration and packages, but it's not designed to create other resources. Option B (AWS::OpsWorks::Instance) is used to create an AWS OpsWorks instance, which is not applicable for the requirement of creating multiple AWS services as a single resource. Option C (AWS::SSM::Document) is used to create an SSM (Systems Manager) document, which is used for automating tasks on instances using SSM, but it does not provide the functionality of creating multiple AWS services as a single resource.
