Solution
The correct option is A By distillation
1,1,1−Trichloroethane
The boiling point of 1,1,1−Trichloroethane
Since the boiling point is only 74oC, the best way to separate the solvent from grease is by distillation.
Chromatography would be too expensive and very cumbersome.
Recrystallization is impractical since the solvent has a melting point of -33 °C
Filtration will only remove particulate matter. If will not remove the grease which is in solution.
