Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A mixture of water and alcohol can be separated by distillation (option C). Distillation works because water and alcohol have different boiling points (100°C for water, 78°C for ethanol), allowing the alcohol to vaporize first. Filtration separates solids from liquids, evaporation leaves solids behind, and decantation separates immiscible liquids of different densities.
