To calculate the number of kcal in the cheeseburger, we need to multiply the number of grams of each macronutrient (fat, carbohydrate, and protein) by their respective caloric values and then add them up.

Fat: 19 g x 9 kcal/g = 171 kcal
Carbohydrate: 20 g x 4 kcal/g = 80 kcal
Protein: 28 g x 4 kcal/g = 112 kcal

Total kcal = 171 + 80 + 112 = 363 kcal

Since the question asks us to round off the energy value for each food group to the tens place, we need to round each value to the nearest ten.

Fat: 170 kcal
Carbohydrate: 80 kcal
Protein: 110 kcal

Total kcal = 170 + 80 + 110 = 360 kcal

Therefore, the answer is B) 360 kcal.
