This is a basic chemistry question. As the question says if you increase the temperature solids such as sugar become more soluble, so if you cool it the opposite will happen and it will become less soluble and may even precipitate out so A is possible.
When temperature rises gasses become less soluble but if the temperature decreases again the opposite will happen and the carbon dioxide gas is more soluble meaning it will stay in solution. Bubbles are evidence of decreased solubility so B is not true.
Water evaporates rapidly at high temperature not cold.
So the answer is A only.

Wow. OK, the first two answers have been distributed by idiots or laymen, either of which shouldn't be answering questions labeled "bio experts", even though this is technically a "chem expert" question.
If you cool a drink down rapidly, sugar may precipitate out, and gas bubbles may form and produce foam. A, and B.
If you drop an ice cube into a soft drink, you will see B happen rather rapidly. However, sugar precipitation will take much cooler temperatures since it takes a lot colder temps to precipitate out micible solids than it does a volatile gas.

The water, since soda is mostly water, will beging to freeze as the temperature is cooling down, pulling the sugar out with it. The carbon dioxide will remain in the can, building pressure, because it is not able to to dissolve in the frozen water and eventually the can will explode, pop, or break open in some form. I hope this helps you...:)

What temp are you heating the soda to? A soft drink at room temp would have no solids, unless you are trying to denature it by heating. So by cooling it down, all you would get would be sugar. The CO2 and H2O would evaporate, leaving a solid. That is my guess.
