Which of the following is considered a pulmonary (choking) agent?

Explanation:
Pulmonary choking agents irritate the respiratory tract when inhaled and can cause rapid coughing, chest tightness, and airway edema. Chlorine gas fits this description because inhalation damages the mucous membranes of the airways, leading to irritation and potentially severe breathing difficulties. The other options belong to different chemical-attack classes: nerve agents like VX and sarin disrupt the nervous system, causing cholinergic effects; mustard gas is a vesicant that mainly causes blistering of skin and mucous membranes. Thus chlorine is the example of a pulmonary choking agent.
