Correct answer is C
The food substance that would produce the highest amount of energy is fat.
Fat is the most energy-dense macronutrient, providing 9 calories per gram. On the other hand, both carbohydrates (including glucose) and proteins provide 4 calories per gram. While amino acids are the building blocks of proteins, they are not a direct source of energy like fat and carbohydrates.
