Solution

The correct option is D Fractional distillation
Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Fractional distillation cannot be carried out for azeotropic mixture as they have constant boiling point.
