Which statement about metal detectors is true?

• A. They can protect the officer from possible injury and prevent the destruction of property
• B. They detect non-metallic items
• C. They are used to weigh items
• D. They are used to scan fingerprints

Answer: (A)

Metal detectors identify metal objects by using a magnetic field to sense disturbances caused by metal. This capability directly supports safety and security by helping to detect weapons or metal items that could injure officers or damage property, allowing screening to stop or deter threats before they escalate. That’s why this statement is true. They don’t detect non-metallic items, they aren’t used to weigh objects, and they don’t scan fingerprints, which is why the other options aren’t correct.
