Which term refers to the most lethal nerve agent described?

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

Answer: (C)

Nerve agents are grouped into G-series and V-series, with the V-series representing the most lethal and persistent class. The term V agent designates this whole class (which includes VX as a member), capturing the idea of the highest potency described. Among the options, using the broader category “V agent” is the best fit because it signals the most lethal family rather than naming a single compound. The other terms refer to specific G-series agents like sarin or tabun, which are highly toxic but generally less potent and less persistent than V-series agents. So, the descriptor for the most lethal nerve agent described is the V agent.
