Explanation

A Trusted Platform Module (TPM) is a dedicated microchip physically embedded on a computer's motherboard. It provides hardware-based security functions including secure storage of cryptographic keys, platform integrity measurement, and support for full-disk encryption (like BitLocker). Because it is hardware-based, keys stored in the TPM cannot be extracted via software attacks. Symmetric key (A) and asymmetric key (B) are cryptographic algorithm types, not hardware. Whole disk encryption (C) is a software feature (though it may leverage TPM hardware). TPM is the only purely hardware security technology listed.
