Which equipment is used to detect contraband in articles such as shoes and clothes?

• A. X-ray scanners
• B. Notepad
• C. Bags
• D. Canines

Answer: (A)

X-ray scanners are used because they let security personnel see inside objects without opening them, revealing hidden items in shoes or clothes. The machine sends X-ray images that show the shape and density of contents, so trained operators can spot unusual items or concealment that isn’t visible on the outside.

A notepad isn’t a detection tool, it’s just for taking notes. Bags are containers that items go into, not detectors of contraband. Canines are an effective detection method, but they’re not equipment—the question specifies equipment, and X-ray scanners fit that category by providing visual evidence through imaging rather than relying on smell or manual search.
