What is a key feature of a Weapon of Mass Destruction?

A Weapon of Mass Destruction (WMD) is specifically designed to cause significant harm to a large number of people, property, or the environment. This particular characteristic sets WMDs apart from other types of weapons, as they can lead to extensive casualties and widespread devastation. Examples of WMDs include nuclear, biological, and chemical weapons, all of which are engineered with the intention of inflicting mass injury and destruction.

In contrast, the other options describe weapons or objects that either do not align with the definition of a WMD or serve completely different purposes. For instance, the mention of sports indicates items that are meant for recreational purposes rather than harm. Personal defense signifies a focus on protecting individuals rather than targeting large groups or areas. Lastly, the suggestion that a WMD has no intended harm contradicts its very nature, which is to cause significant and widespread damage. Thus, understanding that a WMD is intentionally designed for mass injury encapsulates the clear purpose and danger associated with such weapons.
