Answer: Option (B) is the correct answer.
Step-by-step explanation:
A process in which liquid mixture is separated by selective boiling and condensation is known as distillation process.
It is known that boiling point of alcohols is low therefore, when a mixture of alcohol and water is boiled then alcohol will evaporate from the mixture and the water will remain as the liquid.
Therefore, the distillation column will collect the vapors of alcohol separately and hence, it can be separated from water.
Thus, we can conclude that distillation is an effective method for separating a mixture of alcohol and water.
