The correct answer to this question is B, Expand. When water freezes, it can expand. When it expands, it does so by 9%. Water freezes at different degrees, dependent upon the degree metric. In Celius, water freezes at 0 degrees. In Fahrenheit, water freezes at 32 degrees. In Kelvin degrees, it freezes at 273.15.

Despite the difference in degrees for the metric, water freezes at these rates because of the unique characteristics that water molecules have. The molecule for water is H20, which comprises of two hydrogens and one oxygen. These molecules are always moving. When the temperature is more relaxed, they move faster.
