Riot Control Agents are generally used for law enforcement actions but are prohibited under the Chemical Weapons Convention.

• A. Nerve Agents
• B. Blood Agents
• C. Blister Agents
• D. Riot Control Agents

Answer: (D)

Riot control agents are chemicals designed for crowd control and policing, not battlefield warfare. They’re associated with law enforcement use and, under the Chemical Weapons Convention, are treated differently from traditional chemical weapons. Classic warfare agents like nerve agents, blood agents, and blister agents are prohibited as weapons. Riot control agents, however, are allowed for legitimate law enforcement purposes, with misuse as a weapon violating the treaty. That’s why this category best fits the idea of being used for law enforcement rather than prohibited as a chemical weapon.
