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.

Ans 7:

Class : Class 7
carbs, proteins and fats are macronutrients so they should be more than minerals which is a micronutrient but there is no such answer

Ans 8:

Class : Class 6
its wrong as minerals are to be taken in least quantity ,far less than proteins and fat.Kindly rectify the mistake,mineral should have been last in order.
