As water is cooled its density increases 4 degrees Celsius is reached

Explanation:

Thus water being a solvent has various physical and chemical properties it expands as gs and contracts as icy layers until it reaches a freezing point by approx 9% of water density. Schooling of a substance causes water to slow down at a faster rate occupying a smaller rate as hot water is less dense than the room temperature as cold water is denser and will freeze at room temperature. Thus water has to condense to a certain point to produce the desired effects.

Ithink the answer is a or d.
