• ADoor lock and mantrap
• BServer lock and badge reader
• CSecurity guard and entry control roster
• DBiometric lock and hardware token

• A

• B
  5% (2)
• C
  18% (7)
• D
  75% (30)

Explanation

Two-factor authentication (2FA) requires two different categories of authentication factors: something you know, something you have, or something you are. A biometric lock uses 'something you are' (fingerprint, retina scan) and a hardware token uses 'something you have' (a physical device generating a one-time code). This combination represents true 2FA with two distinct factor categories. A door lock and mantrap (A) are physical barriers, not authentication factors. A server lock and badge reader (B) both fall under 'something you have.' A security guard and entry control roster (C) is a procedural control, not a 2FA technical implementation. Option D is the only choice that combines two genuinely different authentication factor types.
