Why each option
Biometrics are classified into two main categories - physiological traits (physical body characteristics) and behavioral traits (action-based patterns).
Psychological is not a recognized standard category of biometrics - the two accepted technical classifications are physiological and behavioral.
Biological is not the standard technical term for body-based biometric traits - the correct classification term is physiological.
Physiological biometrics refer to static physical body characteristics used for identification, such as fingerprints, iris patterns, facial geometry, and hand geometry - these are inherent traits unique to an individual's body.
Behavioral biometrics refer to dynamic patterns in how a person performs actions, such as typing rhythm (keystroke dynamics), gait analysis, and voice patterns - these are traits unique to an individual's behavior over time.
