(1) One of the meals Bill ate contained 80 grams of carbohydrates, 60 grams of protein, and 60 grams of fat.
(2) Bill ate 1500 calories during the day.

(1) One of the meals Bill ate contained 80 grams of carbohydrates, 60 grams of protein, and 60 grams of fat --> we have info only about one meal Bill ate. Not sufficient.
Though from this statement we can find out how much calories did Bill get from this meal:
80 grams of carbohydrates = 4*80 = 320 calories;
60 grams of protein = 4*60 = 240 calories;
60 grams of fat= 9*60 = 540 calories.
(2) Bill ate 1500 calories during the day --> no info about the ratio. Not sufficient.
(1)+(2) To follow his diet Bill should have had 30%*1,500=450 calories from fat but (1) tells that Bill already exceeded this limit in one particular meal, so clearly he did not follow his diet program. Sufficient.

In my humble opinion the answer is A.
B is not sufficient alone becuase even if we know what is the total number of calories we don't know anything about the characteristics of carbo, protein and fat.
If we follow A then we can answer with certainty that he didn't follow his diet. We've enough data to say it with just 1st sentece.
