Explanation / Answer

Ans : c) NaOH

SInce the pH of the solution is determined as 3 , which indicates that the organic compound must be some carboxylic acid. Now NaOH is a base , it reacts with the acid , to form sodium salt of the acid.

So the base (NaOH) must be used to precipitate out the organic compound from the aqueous solution.
