Master Answer- Carbs such pizzas and burgers are very harmful for us. So,they should be consumed in the least amount. Minerals are micronutrients so they should be consumed in less amounts. Fats give us energy so they must be consumed in high quantities. Proteins build our muscles and should be consumed in higher quantities. thus, option D.
