This question was previously asked in
SSC CGL 2017 (Tier 1) Previous Year Paper (16-Aug-2017) (Shift 1)
The correct answer is

Formic Acid

Ants of the family Formicidae inject formic acid (\(\text{HCOOH}\)) when they bite or sting; the acid is responsible for the burning, itchy sensation. The very name "formic" comes from the Latin formica, meaning ant.

Hydrochloric acid occurs in the stomach, acetic acid is the acid of vinegar, and phosphoric acid is used in soft drinks and fertilisers — none of these is secreted by ants.
