The correct answer is D) 1, 2 and 3. Fingerprint scanning is a well-known biometric identification method. In addition to this, iris scanning, retinal scanning, and voice recognition are also established and widely used biometric techniques for identifying individuals based on unique physiological or behavioral characteristics.

Biometric identification uses distinct biological or behavioral traits to verify a person’s identity. Common biometric modalities include fingerprints, iris patterns, retinal blood vessel patterns, facial features, voice characteristics, and gait.

Iris scanning analyzes the complex patterns in the colored part of the eye (iris). Retinal scanning analyzes the unique pattern of blood vessels at the back of the eye (retina). Voice recognition analyzes vocal characteristics, pitch, tone, and speaking patterns. All three listed options (iris scanning, retinal scanning, and voice recognition) are valid methods used for biometric identification.
