Correct:
C
Explanation
Ant bites inject formic acid (chemical name: methanoic acid). A schoolbook example explicitly states that when an ant bites it injects an acidic liquid — formic acid — and that this can be neutralised with a base such as baking soda, explaining the burning sensation and common home remedy [1]. Educational lists of natural sources of common acids also identify ant stings as a source of methanoic (formic) acid, confirming the nomenclature equivalence [2]. Historical and chemical references further note that formic acid was first obtained from ants, and that the bites of some ants inject this simple carboxylic acid into the skin .
