The correct answer is B) Methanoic acid.

When you touch a nettle plant, the stinging hairs (trichomes) inject irritating chemicals into the skin. One of the primary compounds responsible for the burning sensation and rash is methanoic acid, also known as formic acid (HCOOH). Other irritants present include histamine, acetylcholine, and serotonin, which contribute to the inflammatory response.

Formic acid is a simple carboxylic acid found naturally in the venom of ants and bee stings, as well as in nettle stings. Its chemical formula is HCOOH. While other substances are involved in the nettle sting reaction, methanoic acid is a major contributor to the immediate burning pain.
