Which statement correctly differentiates WMD from WMC?

Which statement correctly differentiates WMD from WMC?

• A. WMD cause mass casualties; WMC cause massive destruction
• B. WMD cause massive death or injury, whereas WMC cause large numbers of injuries or deaths
• C. WMD are always nuclear; WMC are always chemical
• D. WMD are domestic; WMC are international

Answer: (B)

The key idea is how harm is produced. Weapons of mass destruction are designed to cause catastrophic, wide‑area effects that lead to mass casualties or total destruction in the target zone. Weapons of mass contamination describe agents or devices that spread hazardous contamination over a large area, exposing many people and causing injuries or deaths through exposure, with a need for decontamination and protective actions. The option that states WMD cause massive death or injury, whereas WMC cause large numbers of injuries or deaths, best captures this difference in how the harm occurs—direct catastrophic effects for WMD versus contamination-driven casualties for WMC. The other statements don’t fit: WMD are not limited to nuclear; WMC are not limited to chemical; and domestic vs international is not what distinguishes the two.
