Answer:
C. 48 calories.
Step-by-step explanation:
The number of calories in 1 gram of carbohydrate is 4 and the number of calories in 1 gram of protein is also 4.
So, calories from carbohydrates = 10 grams x 4 calories/gram = 40 calories
calories from protein = 2 grams x 4 calories/gram = 8 calories
Total calories consumed = 40 calories + 8 calories = 48 calories
Therefore, the answer is option C. 48 calories.
