Which one-day meal plan best follows the dietary principles to meet vitamin needs for a generally healthy adult who consumes dairy?

• A. Breakfast: fruit juice and a donut; Lunch: grilled cheese only; Snack: pretzels; Dinner: macaroni and cheese — because caloric density predicts micronutrient adequacy regardless of food variety.
• B. Breakfast: bagel with cream cheese and black coffee; Lunch: white rice with fried chicken skin; Snack: potato chips; Dinner: beef stew with minimal vegetables — relying on animal fat and refined grains to deliver fat-soluble vitamins primarily through deep frying.
• C. Breakfast: sugar-sweetened cereal fortified with multiple vitamins and skim milk; Lunch: large portion of fries and a soda; Snack: candy bar; Dinner: processed pepperoni pizza — the fortified cereal alone provides all necessary vitamins so other choices do not matter.
• D. Breakfast: oatmeal with milk and blueberries; Lunch: mixed green salad with chickpeas and whole-grain bread; Snack: plain yogurt and an apple; Dinner: grilled salmon, steamed broccoli, and brown rice — combining varied fruits, vegetables, whole grains, lean dairy, and a source of fatty fish for vitamin D and A precursors.
