Why each option
Preventive physical controls are mechanisms that stop unauthorized access or incidents before they occur, distinguishing them from detective or corrective controls.
Biometric access controls prevent unauthorized individuals from entering secured areas by requiring verified physiological credentials before granting access.
Closed-circuit television monitors are detective controls, not preventive - they record and observe activity to identify incidents after or as they happen but do not stop unauthorized access from occurring.
Fire extinguishers are classified as preventive physical controls because they are used to suppress a fire before it spreads and causes catastrophic damage.
Locks and keys physically prevent unauthorized entry into facilities, rooms, or equipment, making them a foundational preventive physical control.
