View Answer

Answer: A

Explanation:

Biometric authentication is considered the most secure access control method because it relies on unique physical or behavioral characteristics of an individual, such as fingerprints, iris scans, or voice recognition. These characteristics are difficult to replicate or forge, making it more difficult for unauthorized individuals to gain access.
