Which option is not one of the four nutrient categories listed?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Minerals

Answer: (D)

The idea being tested is how nutrients are grouped and which items fit into a specific four-category framework used in this context. In that framework, the four categories are carbohydrates, proteins, lipids, and vitamins. Minerals, while essential, belong to a separate group of micronutrients that are inorganic and play different roles (like helping enzymes or maintaining bone and fluid balance) and are not part of this particular four-category list. So minerals isn’t included in those four categories, making it the correct choice for this question.
