Explanation

The correct answer is C. Biometrics. Biometric authentication (fingerprint, retina, facial recognition) is the most secure physical access control method because it relies on unique, inherent biological characteristics that cannot be lost, stolen, shared, or easily duplicated. Smart cards (A) and key fobs (B) are possession-based factors that can be stolen, cloned, or lent to unauthorized individuals. A security guard (D) introduces human error, can be deceived, and does not scale consistently. Biometrics eliminates the risks associated with lost credentials or social engineering.
