Why each option
Biometrics, tokens, and passwords are all common methods used to authenticate a user by verifying their identity through something they are, something they have, or something they know.
Encryption protects data confidentiality and integrity by transforming data into a secure format, but it is not a direct method of user authentication itself.
Biometrics authenticate a user based on 'something you are,' such as a fingerprint, face scan, or iris scan.
A token authenticates a user based on 'something you have,' such as a hardware token, smart card, or software token.
A password authenticates a user based on 'something you know,' such as a secret word, phrase, or PIN.
