Row 1. Here you have the sum  Meat+Beans+Rice, so the expression represent the the total price of all the food.

Row 2. Here you have the sum Beans+Rice. Since both foods are plants, the expression represent the total price of the foods from plants.

Row 3. Here you have the sum  Meat+Beans+Rice again, so the expression represent the the total price of all the food.

Row 4. Here you have the sum Beans+Meat. Since beans and meat are both rich in proteins, the expression represent the total price of the foods rich in protein.

Row 5. Here you have the sum Meat+Rice. Since meat is not a plant and rice is not rich in protein, the correct answer is None of these.

Row 6. Here you have the sum Beans+Meat again just in a different order. Since beans and meat are both rich in proteins, the expression represent the total price of the foods rich in protein.
