The most lethal of all the nerve agents is:

• A. VX
• B. Sarin
• C. Soman
• D. V agent

Answer: (D)

V-series nerve agents are the most lethal because they combine extreme potency with environmental persistence. They inhibit acetylcholinesterase so effectively that tiny amounts can cause deadly cholinergic disruption. Their high lipid solubility lets them penetrate skin easily, and they tend to remain in the environment longer than many G-series agents, increasing the chance of exposure. VX is the best-known example of a V agent and is extraordinarily toxic at very small doses, which is why this class is considered more lethal than agents like sarin or soman. Sarin and soman are dangerous too, but they are more volatile and less persistent, leading to shorter exposure windows. So the most lethal nerve agent category is the V agent.
