Explanation

Option C is correct because physical security requires tangible barriers that prevent unauthorized physical access to facilities where company information is stored or processed. Break-resistant glass, reinforced doors, proper locks, frames, and hinges are all physical controls that stop intruders from entering restricted areas.

Why the distractors are wrong:

• A (Air-conditioning) is an environmental control that supports hardware uptime - it doesn't restrict who can enter a space.
• B (Username and password) is a logical (digital) security control, not a physical one - it protects access to systems, not buildings or rooms.
• D (Prohibiting USB sticks) is a policy/administrative control targeting data exfiltration, not physical access to the premises.

Memory tip: Think of the word physical literally - if you can touch it and it blocks a body from entering, it's a physical security control. Locks, doors, and glass are things you physically interact with to gain entry; passwords and policies exist only in rules or software.
