Question

$125,000 question: which gas caused blisters all over the body? a. chlorine gas b. mustard gas c. hydrochloric gas d. intestinal gas

Explanation:

Mustard gas is a chemical warfare agent. When it comes into contact with the skin, it can cause severe blistering. Chlorine gas mainly affects the respiratory system (causing coughing, shortness of breath etc.). Hydrochloric gas is highly corrosive but not typically associated with widespread blistering all over the body in the context of chemical warfare - like scenarios. Intestinal gas is a normal physiological product (e.g., from digestion) and not a gas that causes blisters.

Answer:

B. Mustard Gas
