I would use fractional distillation to separate A from B. B would come off first because it has the lowest boiling point. A has stronger forces between its molecules, so it needs more heat to boil.

Fractional distillation works because A and B have different boiling points and different forces of attraction between their molecules.

Since C is insoluble in water, I would heat the mixture to boil off A and B, leaving C behind. I would then filter to remove C, wash it with water, and dry it to get it pure.
