What are Weapons of Mass Destruction (WMD)?

• A. Weapons designed for personal self-defense.
• B. Non-lethal crowd control devices.
• C. Weapons designed to bring about mass casualties and/or damage to property and infrastructure.
• D. Educational tools for emergency responders.

Answer: (C)

Weapons of Mass Destruction are weapons designed to cause mass casualties and/or extensive damage to property and infrastructure. They’re defined by the scale of harm they can unleash across people and environments, not just by how lethal a single device is. This category includes nuclear, chemical, biological, and radiological weapons, and devices that spread these hazards, because each has the potential to affect large populations and disrupt communities for long periods. In emergency response terms, incidents involving WMD require specialized preparation and procedures—protection, decontamination, secure isolation, and coordinated multi-agency response—to minimize exposure and manage the consequences.

The other descriptions don’t fit because they involve far smaller-scale or different purposes: personal defense tools are intended for individual use; non-lethal crowd control devices aim to minimize harm and avoid mass casualties; educational tools are not weapons at all.
