Which gas is a type of blood agent that has an almond-like odor and is colorless?

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

Answer: (C)

Cyanide gas fits this description because it’s a blood agent that is colorless and is traditionally linked with a bitter almond odor. Blood agents interfere with cellular respiration by inhibiting cytochrome c oxidase, so cells can’t use oxygen properly, leading to rapid toxicity. Chlorine gas is a choking agent with a sharp smell, not a blood agent. Dushaqiang (TETS) is a different type of toxic agent (not a blood agent). While “blood agents” covers cyanide compounds as a group, the specific gas that matches all the clues is cyanide gas.
