The thermostat in a refrigerator filled with cans of soft drinks malfunctions and the temperature of the refrigerator drops below 0 °C. The contents of the cans of diet soft drinks freeze, rupturing many of the cans and causing an awful mess. However, none of the cans containing regular, non-diet soft drinks rupture. Select the statement or statements below that best describe this behavior.

a. As the temperature drops the solubility of the dissolved carbon dioxide gas decreases in the diet soft drinks. The pressure caused by this released gas builds up and finally ruptures the can.
b. Water expands on freezing. Since water is the principle ingredient in soft drinks when the soft drink freezes it will rupture the can.
c. There is more water in diet soft drink so they will freeze point of the solution sufficiently so that the solution does not freeze.
d. Diet soft drink are inherently messier than non diet soft drinks.
