Solution

The correct option is B
Fractional distillation

The fractional distillation process is based on the difference of boiling points between the mixtures of two or more substances which is being used for the distillation. As the different component of crude oil have different boiling points so with the passage of heat different impurities show different boiling point and get separated easily with the help of outlet pipe.
