Which category of nutrients provides energy to the body?

• A. Minerals
• B. Vitamins
• C. Water
• D. Macronutrients

Answer: (D)

Energy comes from macronutrients—the carbohydrates, proteins, and fats we eat. These nutrients supply calories that the body uses for all activities and bodily processes. Minerals and vitamins do not provide calories themselves; they act as helpers in metabolic reactions. Water has no caloric value but is essential for hydration and metabolism. So, among the options, macronutrients are the energy-providing category.
