If there are 100 grams of protein, and each has 4 Kcals, that's 400 calories. Subtract that from the total Kcals: 1250-400=850, and that's the number of Kcals from fat. Now divide the calories by the number of Kcals per gram, 850/7=121.42, which rounds to 121, letter B

B - 121
100 grams of protein = 400 kilocalories
1250 - 400 = 850 kilocalories in that burger from fat.
850 / 7 = 121 grams of fat
Didn't have to look anywhere for the answer, just do the math. Everything was given to you.

You cannot tell how many fat calories are in something by measuring the protein. They're separate things.
