Backends in Terraform are responsible for storing and retrieving state data.

• A. They validate configurations
• B. They manage external plugins
• C. They store and retrieve state data
• D. They run providers

Answer: (C)

Backends determine where Terraform stores and retrieves state data. The state is a snapshot that tracks all managed resources, their IDs, and metadata Terraform needs to plan and apply changes correctly. A backend can store this state locally or remotely, and remote backends often provide locking to prevent concurrent writes, which is essential for teamwork. This role is distinct from validating configurations, which happens during planning and applying, and from how Terraform loads and runs provider plugins, which are responsible for creating, updating, and destroying resources. So the statement that backends store and retrieve state data best captures their purpose.
