Which item is listed as a potential sharps/contraband?

• A. Knives
• B. Gum
• C. Plastic bags
• D. Batteries

Answer: (A)

In safety screening, items that could be used as sharp tools or as contraband are identified to prevent harm. Knives have blades that can cause cuts or be used as weapons, so they are a clear example of potential sharps/contraband and are typically prohibited or closely controlled. Gum isn’t sharp and doesn’t pose the same risk, though it may be restricted for other reasons in some settings. Plastic bags can be a concern for choking or concealment but aren’t inherently sharp. Batteries present other safety hazards but don’t fit the “sharps” category. So, knives are the item that fits the criterion of potential sharps/contraband.
