Why each option
The question asks to identify a method of authentication that uses unique biological or physical characteristics of an individual.
A smart card is a 'something you have' authentication factor, requiring physical possession of the card.
A password is a 'something you know' authentication factor, relying on secret information the user remembers.
A retina scan is a biometric authentication method that identifies an individual by analyzing the unique pattern of blood vessels at the back of their eye. Biometrics relies on 'something you are' for authentication.
A personal identification number (PIN) is a 'something you know' authentication factor, typically a short numeric password.
