Explanation

Key fobs (D) are compact hardware devices that serve a dual purpose: they are widely used as RFID/proximity tokens for physical building entry (swiped or tapped at readers) and can also function as OTP (one-time password) generators for computer or network authentication. While smart cards (A) and PIV cards (B) can also handle both functions, key fobs are the most commonly cited example of a single device covering both physical and logical access in exam contexts. Hardware tokens (C) are typically software/authentication-only devices without a physical-access component.
