Explanation
Encryption at rest protects data stored on physical media (hard drives, SSDs, USB drives, backups) so that if the hardware is stolen or physically seized, the data remains unreadable without the encryption key. This is the primary security rationale for encrypting data at rest. Option A is incorrect - encryption does not facilitate or prevent OS changes by users. Option B is a drawback, not a benefit. Option C describes remote wipe, which is a separate capability unrelated to encryption at rest.
