Solution

The correct option is C Bitter $$\quad$$ Formic acid $$\quad$$ Baking soda
Acids are sour in taste and when ants bite they inject formic acid ($$\text{HCOOH}$$) 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.
