Explanation
Two-factor authentication (2FA) requires exactly two distinct authentication factors from different categories. 'Something you know' is a knowledge factor (e.g., a password or PIN), and 'something you are' is an inherence factor (e.g., a fingerprint or retina scan - biometrics). Combining two different factor types is the definition of two-factor authentication. Biometrics (choice A) alone is only one factor. Kerberos (choice B) is a network authentication protocol, not a factor type. A token (choice C) represents 'something you have,' not what is described here. Since both required factors span two different categories (knowledge + inherence), the answer is two-factor authentication.
