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 |
| 2. | 1 | 2 | 3 | 4 |
| 3. | 1 | 4 | 3 | 2 |
