Suggested Answer: D 🗳️
AWS Cloudformation is an application management tool which provides application modelling, deployment, configuration, management and related activities.
AWS CloudFormation provides a WaitCondition resource which acts as a barrier and blocks the creation of other resources until a completion signal is received from an external source, such as a user application or management system.
