Explanation

Biometric authentication uses unique physical or behavioral characteristics of a person to verify identity. A voiceprint (voice recognition) is a behavioral biometric-it measures the unique characteristics of a person's voice. The other options (physical key + password, email + password, OTP + PIN) are combinations of 'something you have' and 'something you know,' not biometrics. Other biometric examples include fingerprints, retina scans, and facial recognition.
