Weapons of mass destruction include which of the following?

Weapons of mass destruction (WMD) are typically defined as weapons that can cause large-scale harm or destruction, often indiscriminately affecting civilians and military personnel alike. They primarily encompass nuclear, biological, and chemical weapons.

Sarin, a highly toxic nerve agent, falls under the category of chemical weapons, which are recognized as a type of WMD. Its ability to affect large populations quickly and lethally makes it a significant threat in terms of mass destruction. The use of sarin in attacks, such as those seen in Japan during the 1995 Tokyo subway incident, exemplifies its categorization as a WMD due to its potential for mass casualties and widespread panic.

Other options presented do not fit the definition of WMD. Rocket-propelled grenades and precision-guided munitions are conventional weapons that, while potentially deadly, do not have the same capacity for mass destruction as chemical, biological, or nuclear weapons. Semtex, a type of plastic explosive, is also considered a conventional explosive rather than a WMD, despite its potency in smaller scale attacks.
