The answer is a.
Antifreeze (ethylene glycol) forms a solution with a much lower freezing point. It also has a higher boiling point, therefore the vapor pressure is lower.

A:
Ethlyene Glycol has a very low melting point - 12.9 C
with a very high boiling point + 197.3
It also acts as a dehydrator, removing water vapor from boiling mixtures.
