Explanation

TPM is a dedicated security chip that stores cryptographic keys, enabling BitLocker to encrypt the hard drive without requiring a USB key at every boot.

Common mistakes.

A. Virtualization extensions (Intel VT-x / AMD-V) enable hypervisor support for running virtual machines and have no direct role in BitLocker drive encryption.
B. A BIOS password restricts access to firmware settings but does not provide the cryptographic key storage that BitLocker requires for full-disk encryption.
D. CMOS is a small battery-backed memory chip that stores BIOS configuration settings such as date and time; it has no cryptographic capability and is unrelated to BitLocker.
