Solution

The correct option is C Bitter Formic acid Baking soda
Acids are sour in taste and when ants bite they inject formic acid (HCOOH) into the victim. Hence II is Formic acid.
This formic acid can be neutralized by a base. Baking soda is sodium bicarbonate which is alkaline in nature and can neutralize the formic acid. Hence III is Baking soda.
It is bitter in taste (I).

Hence, option B is correct.
