B Correct answer
Explanation

Water and alcohol form a homogeneous mixture that cannot be separated by filtration, decantation, or simple evaporation. Distillation works because water (boiling point 100°C) and ethanol (78°C) have different boiling points, allowing them to be separated through controlled heating and condensation.
