Sophia travels a lot and worries that her laptop containing confidential documents might be stolen. What is the best protection that will work for her?
The correct answer is A. Disk encryption. Full disk encryption protects confidential data on a stolen laptop by rendering the entire drive unreadable without the encryption key, regardless of how the attacker accesses the hardware.

Why each option
Full disk encryption protects confidential data on a stolen laptop by rendering the entire drive unreadable without the encryption key, regardless of how the attacker accesses the hardware.
Disk encryption, such as BitLocker or FileVault, encrypts all data on the drive at rest. Even if the laptop is stolen and the drive is removed or booted from external media, the data remains inaccessible without the correct decryption credentials or key. This is the only control that protects data independently of the operating system login.
A BIOS password prevents unauthorized booting but can be bypassed by removing the hard drive and reading it in another system, leaving data fully exposed.
Hidden folders only obscure file locations within the OS and provide no protection if the attacker boots from external media or accesses the drive directly.
Password-protected files only secure individual files and the protection strength varies widely by application, leaving unprotected files and OS artifacts fully exposed.
