"WebAug 8, 2016 · Pure ethylene glycol has a freezing point of −12.9∘C, and water's freezing point is 0∘C. So, the solution's freezing point should actually be below 0∘C (what occurs is freezing point depression due to colligative properties of adding solutes into a solvent, so the freezing point should drop). We can eliminate all but B, −20.1∘C. " - Freezing point of ethylene glycol
