Which substance is a clear liquid with odorless properties?

• A. Dushaqiang (TETS)
• B. Chlorine gas
• C. Blood agents
• D. Nerve agents

Answer: (D)

Nerve agents can be present as colorless, odorless liquids at room temperature, which makes them especially dangerous because you may not detect them by sight or smell. A well-known example is VX, a clear, odorless liquid that can contaminate surfaces and evaporate slowly, creating a silent hazard. In contrast, chlorine is a gas with a sharp odor, blood agents like hydrogen cyanide typically have a detectable odor (bitter almonds) or are gases, and Dushaqiang (TETS) is not the classic clear, odorless liquid associated with this hazard. So the description fits nerve agents best.
