To find the percentage of calories that come from sugar, we need to first find the total number of calories that come from the 13 grams of sugar. 
1 gram of sugar provides 4 calories, so 13 grams of sugar provides 52 calories (13 x 4 = 52). 
Next, we need to find what percentage of the total 240 calories this is. 
52/240 x 100 = 0.2166 x 100 = 21.66% 
So, approximately 22% of the calories in a serving come from sugar. Therefore, the correct choice is B.
