Which statement best describes micronutrients?

• A. Provide calories and energy
• B. Build muscle mass
• C. Regulates and controls body processes; vitamins, minerals, and water
• D. Supply energy quickly during exercise

Answer: (C)

Micronutrients are needed in small amounts to regulate body functions and metabolism. They include vitamins and minerals, and water also plays a key regulatory role in hydration, fluid balance, and numerous biochemical reactions. They do not provide calories; instead they act as cofactors for enzymes and support processes like energy production, growth, and maintenance of homeostasis. That’s why the statement describing micronutrients as regulators of body processes and listing vitamins, minerals, and water is the best fit. The other options describe energy provision or muscle-building, which are functions of macronutrients rather than micronutrients.
