The thermostat in a refrigeraor filled with cans of soft drinks malfunctions and the temperature drops to below 0 degree Celsius. The contents of the cans of diet sodas freeze, rupturing many of the cans. However, none of the cans containing regular soda rupture. Select the statement or statements below that best describes this behavior.

a. As the temperature drops, the solubility of the dissolved CO2 gas decreases in the diet soda. The pressure caused by this released gas builds up and finally ruptures the can

b. Water expans on freezing. Since water is the principle ingedient in soft drinks, when the soft drink freezes it will rupture the can

c There is more water in diet soda so they will freeze sooner than the non-diet soda

d The sugar in the non-diet soda lowers the freezing point of the solution sufficiently so that the solution does not freeze.

e. Diet soft drinks are inherently messier than non-diet soft drinks
