The Correct Option is A

Solution and Explanation

Simple distillation: for liquids with a large boiling point difference or those that decompose - chloroform + aniline (III).
Fractional distillation: for liquids with close boiling points - diesel + petrol (I).
Distillation under reduced pressure: for liquids that decompose below their boiling point - glycerol + spent-lye (IV).
Steam distillation: for steam-volatile, water-immiscible liquids - aniline + water (II).
A-III, B-I, C-IV, D-II: option (1).
