Which option is NOT listed as a screening device in the material?

• A. Magnetometers
• B. X-ray machines
• C. Hand scanners
• D. Metal detectors

Answer: (D)

The question is asking which screening devices are described in the material. The material lists magnetometers, X-ray machines, and hand scanners as screening tools, while metal detectors are not included in that list. Each listed device serves a different screening approach: magnetometers detect magnetic disturbances to reveal metal items, X-ray machines inspect the contents of bags or packages, and handheld scanners provide portable checks. Since metal detectors aren’t mentioned in the material, that option is the one that doesn’t fit.
