Explanation
Biometrics authenticates identity using inherent physical or behavioral characteristics of the individual - such as fingerprints, iris patterns, facial geometry, or voice - making it the authentication method that relies on 'something you are.' Social engineering (A) is a manipulation attack technique, not authentication. Kerberos v5 (B) is a network authentication protocol based on secret keys and tickets, not physical traits. CHAP (Challenge Handshake Authentication Protocol) (D) authenticates using a shared secret/password - something you know, not something you are.
