Match the type of mixture of compounds in Column I with the technique of separation/purification given in column II.

Column I Column II
A. Two solids which have different solubilities in a solvent and which do not undergo a reaction when dissolved in it 1. Steam distillation
B. Liquid that decomposes at its boiling point 2. Fractional distillation
C. Steam volatile liquid 3. Crystallisation
D. Two liquids that have boiling points close to each other 4. Distillation under reduced pressure

Codes:

A B C D
1. 3 4 1 2
