Answer:
(A) Chloroform
Explanation:
When two non-miscible liquids are put in a separatory funnel, the denser liquid will be the bottom layer of the extraction.
An aqueous solution of benzoic acid will have a density somewhat higher than the density of the pure solvent, which is water (water density ≅ 1g/cm³).
Chloroform is denser than water and is the densest among the options, so the correct answer is A).
