Explanation

Two-factor authentication (2FA) requires exactly two distinct authentication factors from different categories. Here, the username and password together represent 'something you know' (knowledge factor), and the fingerprint scan represents 'something you are' (biometric/inherence factor). Since two different factor types are used, this is 2FA. Single sign-on (A) is about accessing multiple systems with one login, not about multiple factors. Network access control (B) governs which devices can join a network. PKI authentication (C) uses digital certificates and key pairs.
