O A. Different densities
O B. Different molecular masses
C. Different boiling points
O D. Different molecular sizes

Different boiling point.

Because in distillation the substance with lower boiling point is evaporated, leaving the other material(s).

Answer 2

Distillation relies on different boiling points to separate out parts of a solution.
