D.

Device data encryption

Suggested answer: D

Explanation:

Detailed

Device data encryption (Option D) ensures that even if the device is lost or stolen, its data cannot be accessed without proper credentials, even while offline. Encryption protects the data at rest, making it unreadable without the decryption key.

Remote wipe (Option A) requires the device to be online to receive the wipe command.

Mandatory screen locks (Option B) provide a layer of security but can be bypassed with physical access in some cases.

Location applications (Option C) help track the device but don't protect data.
