C Correct answer
Explanation

Antihistamines are the class of drugs that block histamine receptors and are used to treat allergic reactions. 'Histamines' are the inflammatory chemicals that cause allergy symptoms, 'histamine inhibitors' is not the standard terminology, and 'antimetabolites' are cancer/immune-suppressing drugs unrelated to allergy treatment. Antihistamines work by blocking the H1 histamine receptors to prevent allergic symptoms.
