Solution

The correct option is C $A q . H C l$
The reagent selected should be such that only one of components to be separated reacts with it.
$A n i l i n e + a q H C l \to s a l t$ , which is water soluble $N i t r o b e n z e n e + a q . H C l \to$ no reaction
$∴ a q H C l$ is used to separate aniline and nitrobenzene.
