Answer

Explanation:

Step1: Calculate calories from carbohydrates

Carbohydrates provide 4 calories per gram. So for 1.1 grams of carbohydrates, the calorie - count is $1.1\times4 = 4.4$ calories.

Step2: Calculate calories from protein

Protein provides 4 calories per gram. For 13 grams of protein, the calorie - count is $13\times4=52$ calories.

Step3: Calculate calories from fats

Fats provide 9 calories per gram. For 11 grams of fats, the calorie - count is $11\times9 = 99$ calories.

Step4: Calculate total calories

Add up the calories from carbohydrates, protein, and fats: $4.4 + 52+99=155.4$ calories.

Answer:

C. 155.4 calories
