Solution

The correct option is A
The difference in the boiling point of the liquids is less than 30^oC.

Fractional distillation is used to separate mixture in which constituent liquids has boiling point difference less than 30^oC. We can separate mixture of ethyl alcohol and water by fractional distillation because boiling point of ethyl alcohol is 78.4^oC and that of water is 100^oC.
