Is this A?
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules?

The density of ice would be greater than the density of liquid water, and ice would not float.
Ice would form in layers, and liquid water would get trapped in between the layers.
Liquid water would have a higher specific heat, making it less likely to undergo vaporization.
The freezing point of water would decrease, making ice more difficult to form.
I think it might be A or D I hope that helps you narrow that down a little bit more.
