Which term describes an item designed to prevent detection of stolen merchandise by a retail theft detector?

• A. Retail theft detector
• B. Shielding or deactivation instrument
• C. Security tag
• D. Alarm badge

Answer: (B)

Defeating a store’s anti-theft system with a device.

This term describes a tool that is used to shield or deactivate merchandise so the security detector won’t trigger. It directly refers to the instrument’s purpose—to bypass the detection mechanism—rather than to the detector itself, the security tag, or an unrelated item like an employee badge. The shielding or deactivation instrument covers both shielding the item from the detector and deactivating the tag, which is why it’s the best fit for describing an item designed to prevent detection.
