Explanation

Biometrics is the authentication method that uses unique physical or behavioral characteristics - such as fingerprints, retina scans, facial recognition, or voice patterns - to verify identity. PKI (Public Key Infrastructure) uses digital certificates and key pairs for authentication. Mutual authentication requires both parties (client and server) to authenticate each other, using mechanisms like certificates or tokens. Kerberos is a network authentication protocol that uses tickets and a trusted third-party Key Distribution Center (KDC). None of these three involve physical traits - only biometrics does.
