The Correct Option is B

Solution and Explanation

The correct answer is option (B) : aq. NaHCO3 + n-hexane
PhCOOH and PhCH3 can be separated by Aq. NaHCO3 + n-hexane. This method is the acid-base extraction method. 
When NaHCO3 is added to the mixture, benzoic acid will react with NaHCO3( a weak base) to form soluble sodium benzoate. 
After this, the non-aqueous layer will contain toluene.
