Suggested Answer: C 🗳️
AWS Cloudformation is an application management tool which provides application modelling, deployment, configuration, management and related activities. The
AWS Cloudformation stack is a collection of AWS resources which are created and managed as a single unit when AWS CloudFormation instantiates a template.
If any of the services fails to launch, Cloudformation will rollback all the changes and terminate or delete all the created services.

C seems like the right answer. I took the DVA exam a few weeks back. Seems along the lines of the questions on that exam.
