B Correct answer
Explanation

Evaporation separates sugar from water because when you heat a sugar solution, water (with lower boiling point) evaporates into the air, leaving solid sugar crystals behind. This works because sugar is non-volatile and has a much higher boiling point than water. Cream separation uses centrifugation or churning, alcohol-water separation requires distillation due to closer boiling points, and sand-water would use filtration or sedimentation.
