Explanation

Authentication is categorized into three factors: something you know (e.g., passwords/PINs), something you have (e.g., hardware/software tokens, smart cards), and something you are (e.g., biometrics like fingerprints or retina scans). Option C - Passwords, Tokens, and Biometrics - maps cleanly to all three authentication factors. Options A and D mix categories imprecisely (voice fingerprinting and retina scans are both biometrics), and Option B (Memory Cards and Smart Cards) uses two 'something you have' items, missing biometrics entirely.
