To calculate the number of kilocalories in a serving of food, we need to use the following conversion factors:

1 g carbohydrate = 4 kcal
1 g protein = 4 kcal
1 g fat = 9 kcal

Using these conversion factors, we can calculate the total number of kilocalories in one serving as follows:

Carbohydrates: 15 g x 4 kcal/g = 60 kcal
Protein: 15 g x 4 kcal/g = 60 kcal
Fat: 4 g x 9 kcal/g = 36 kcal

Total: 60 kcal + 60 kcal + 36 kcal = 156 kcal

Therefore, the best choice is C, with 156 kilocalories in one serving.
