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 in security screening are used to find metal objects that could cause harm. By quickly flagging hidden weapons or metal items, they help keep officers safe and reduce the risk of property damage during searches or encounters. That practical safety role is why this statement is the best description of what metal detectors do.

They do not weigh items, they do not scan fingerprints, and they do not reliably detect non-metallic items. So the option that emphasizes protecting the officer and preventing property destruction aligns with how metal detectors are used in real-world security situations.
