You have a mixture of three liquids A, B and C. There is a large difference in the boiling points of A and rest of the two liquids i.e., B and C. Boiling point of liquids B and C are quite close. Liquid A boils at a higher temperature than B and C and boiling point of B is lower than C. How will you separate the components of the mixture?

Options

1. AUse simple distillation to separate liquid A first, then use fractional distillation to separate B and C.
2. BUse fractional distillation to separate liquid A first, then use simple distillation to separate B and C.
3. CUse fractional distillation to separate liquids B and C first, then use simple distillation to separate A.
4. DUse fractional distillation only.
