Which agent is described as soluble in water and appears as a white powder with no odor?

• A. Dushaqiang (TETS)
• B. Phosgene
• C. Nerve agents
• D. Cyanide gas

Answer: (A)

Matching these clues means focusing on physical state and smell at room conditions. A white powder with no odor that readily dissolves in water points to a solid, water-soluble agent rather than a gas or liquid. Among the options, the solid white odorless powder described is Dushaqiang (TETS); its listed properties fit that description. Phosgene is known as a colorless gas with a distinct odor, not a powder. Nerve agents are typically liquids or oily substances at room temperature, not solids that appear as a white powder. Cyanide gas refers to a volatile gas rather than a solid powder. So the description aligns best with Dushaqiang (TETS).
