Weapons of Mass Destruction (WMD) are:

• A. Small hand-held items with minor effects.
• B. Used only for military parades.
• C. Primarily domestic consumer products.
• D. Designed to inflict serious injury or death across a large group of people.

Answer: (D)

WMDs are weapons designed to cause mass casualties and widespread disruption. The key idea is the scale of harm—injury or death over a large number of people or across a broad area, often with rapid and catastrophic impact. That’s why the option describing a weapon as something designed to inflict serious injury or death across a large group of people is the best fit. The other descriptions don’t align with this definition: WMDs aren’t small hand-held items with minor effects, aren’t used only for parades, and aren’t primarily domestic consumer products. In practice, such weapons require high-level protective measures, specialized response, and coordinated decontamination and evacuation considerations.
