The number of calories in a gram of refined cane sugar is the same as in an equal amount of fructose, the natural sugar found in fruits and vegetables. Ttherefore, a piece of candy made with a given amount of refined cane sugar is no higher in calories than a piece of fruit that contains an equal amount of fructose. The reasoning in the argument is flawed because the argument
A: presupposes what it sets out to establish, that fruit does not differ from sugar-based candy in the number of calories each contains
B: fails to consider the possibility that fruit might contain noncaloric nutrients that candy does not contain
C: overlooks the possibility that sugar might not be the only calorie-containing ingredient in candy or fruit
D: presupposes that all candy is made with similar amounts of sugar
