Best answer
Correct option is (a) Vacuum distillation

Explanation: To remove the hexane from oil, the miscella is treated in a vacuum distillation process. The hexane is evaporated during the distillation method which is condensed and separated from water in a decanter. The recovered hexane is then reused in the extractor.
