A. B. C. D.

Correct Answer - B.

AWS CloudFormation Change Set can be used to preview changes to AWS resources when a stack is executed.

Option A is incorrect as AWS CloudFormation Drift Detection is used to detect any changes made to resources outside of CloudFormation templates.

It would not be able to preview changes that will be made by CloudFormation Templates.

Option C is incorrect as these are groups of stacks that are managed together.

Option D is incorrect as these Intrinsic Functions are used for assigning values to properties in CloudFormation templates.

The feature that can be used to preview changes to be made to an AWS resource which will be deployed using the AWS CloudFormation template is AWS CloudFormation Change Sets.

AWS CloudFormation is a service that allows users to model and provision AWS resources with an easy-to-use template. Change Sets, a feature of AWS CloudFormation, helps to preview the changes that will occur to your AWS infrastructure before you deploy them.

When creating a Change Set, AWS CloudFormation analyzes the differences between the current stack and the updated template. The Change Set then provides a detailed report that outlines the proposed changes, such as which resources will be created, modified, or deleted, and the estimated impact on your resources.

Change Sets can help you to evaluate the potential impact of changes to your infrastructure, review the changes before applying them, and avoid any unexpected changes that could lead to service disruptions or other problems.

AWS CloudFormation Drift Detection is another feature that can be used to detect any differences between a stack's actual configuration and its expected configuration. However, it is not used for previewing changes to be made to a resource.

AWS CloudFormation Stack Sets is a feature that allows you to deploy CloudFormation stacks across multiple accounts and regions. It is also not used for previewing changes.

AWS CloudFormation Intrinsic Functions are built-in functions that can be used in a CloudFormation template to create dynamic templates. They are not used for previewing changes either.
