A student is shown the molecular formula of a nutrient that contains carbon and hydrogen atoms bonded to a carbon backbone. Based on this information, which classification is most appropriate and why?

• A. Non-nutrient contaminant, because any carbon-containing compound in food is considered a pollutant rather than a nutrient
• B. Inorganic micronutrient, because only minerals and water supply essential inorganic elements and this formula implies a mineral salt
• C. Organic nutrient, because the presence of a carbon backbone qualifies it as organic (examples include carbohydrates and vitamins)
• D. Essential mineral because all essential nutrients must be inorganic to be stored in bone and tissues

Answer: (C)
