The correct answer is: Doors and mechanical locks.

Doors and mechanical locks are a common physical access control method employed on a building. This is because they are simple, cost-effective, and provide a straightforward way to prevent unauthorized access. Physical access control involves measures taken to ensure that only authorized individuals can enter a specific area or building. It comprises of locks, security doors and other barriers to entry. Among these methods, doors and mechanical locks are the most basic and commonly used.
