To calculate the total kcals in the snack bar, we need to determine the calories from each macronutrient. Carbohydrates provide 4 kcals per gram, so 17 grams of carbs provide 68 kcals. Fat provides 9 kcals per gram, so 1 gram of fat provides 9 kcals. Protein also provides 4 kcals per gram, so 1 gram of protein provides 4 kcals. Adding these together, we get a total of 81 kcals in the snack bar. Therefore, the best choice is C.
