b: Explosive.
Explosives are typically used to produce concussions that can destroy property, inflect injury, and cause death. The energy released by an explosion can generate a shockwave that produces a sudden and intense spike in air pressure, which in turn causes rapid displacement of air molecules around the explosion site. The force of the explosion can damage structures, vehicles, and other objects nearby, and can also cause internal injuries to individuals in the vicinity of the blast. Thus, the use of explosives as a weapon carries a high level of risk and potential harm to people and property.
