Data at rest encryption is primarily concerned with protecting data while it is

Explanation:
Data at rest encryption protects information that is stored and not actively being used, such as files on a disk, databases on storage systems, USB drives, or backups. If a device is lost or stolen, the encrypted data remains unreadable without the proper keys, preserving confidentiality. This is different from data in transit, which is protected while moving over a network, and from data in use, which is in memory during processing. So, the best description is protecting data stored on disk or other media.
