Solution

The correct option is C Benzoic acid
Toluene is a neutral compound and aniline is a base. They do not react with sodium bicarbonate which acts as a weak base.
Phenol is a very weak acid and does not react with sodium bicarbonate.
Benzoic acid reacts with sodium bicarbonate to form water soluble sodium benzoate. On neutralization, sodium benzoate regenerates benzoic acid.
