Which of the following is NOT a blood agent?

Explanation:
Blood agents work by disrupting the body’s use of oxygen, producing rapid systemic hypoxia. Hydrogen cyanide and cyanogen are classic examples because they interfere with cellular respiration, leading to quick symptoms as tissues are starved of oxygen. Arsine is an extremely toxic gas that causes severe hemolysis and systemic damage, but its primary action is not the same rapid cellular respiration blockade characteristic of blood agents. Mustard gas, by contrast, is a blister agent (vesicant) that damages skin, eyes, and mucous membranes with a delayed onset, not by depriving tissues of oxygen. Therefore, mustard is not a blood agent.
