Answer:
The ether layer will contain aniline and toluene after the extraction.
Explanation:
A solvent extraction is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent (Ether, in this case).
PhCO₂H (Benzoic acid) reacts with NaOH to form benzoate ion that is very soluble in water but poorly soluble in ether. That means PhCO₂H will be in the aqueous layer.
PhNH₂ (Aniline) is very soluble in organic solvents as ether but poorly soluble in water,
PhCH₃ (Toluene) is soluble in ether but insoluble in water.
That means the ether layer will contain aniline and toluene after the extraction.
