Nerve agents are classified into G-series (gases) and V-series (viscous liquids). Which statement is true?

• A. G-series are gases
• B. V-series are viscous liquids
• C. Both statements are true
• D. Neither statement is true

Answer: (C)

Understanding how nerve agents are categorized by their physical state at room temperature helps explain why this statement is true. G-series agents are gases at room temperature, which is why they’re described as gaseous nerve agents. V-series agents are viscous liquids at room temperature, appearing oily and thick and tending to persist on surfaces. Since each generalization holds—that G-series are gases and V-series are viscous liquids—the statement that both are true is correct. The other options would imply one or neither of these facts, which doesn’t match how these agents behave under typical conditions.
