Solution

The correct option is A fractional distillation
If the boiling points of two liquids are close to each other, they are separated by fractional distillation. Usually the difference in the boiling points of two liquids to be separated by fractional distillation is 30 deg C or more. Thus, carbon tetrachloride ( b.pt 350 K) and anisole ( b.pt 427 K) can be separated by fractional distillation.
