B) Gas bubbles may form and produce foam. C) Water may evaporate rapidly.

I think this is a poor question because most of us know that sugar DOESN'T ppt when a soft drink is cooled. Of course, the question doesn't say how much it is cooled. At any rate, from the question, we know b can't be right an c can't be correct so that leaves only a. But I wouldn't EXPECT that to happen unless we cool it WAY down.
