Which of the following is NOT a form of security?

• A. Screen
• B. Guard
• C. Patrol
• D. Local

Answer: (C)

Understanding what counts as a form of security versus an activity helps here. A form of security refers to a defined method, role, or system used to protect people or property—like screening, which is the process of checking and filtering; a guard, which is a person assigned to protect; or local security, indicating a specific jurisdiction or organizational approach. Patrol, on the other hand, is an activity or procedure carried out to monitor an area. It’s something security teams do to enforce protection, not a distinct security type itself. So patrol is the one that doesn’t fit as a form of security.
