A liquid compound (X) can be purified by steam distillation only if it is:

1. Steam volatile, immiscible with water.

2. Not steam volatile, miscible with water.

3. Steam volatile, miscible with water.

4. Not steam volatile, immiscible with water.

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