E Correct answer
Explanation

Dietary nutrients are substances that provide energy or are essential for growth, maintenance, and repair of body tissues. Proteins, vitamins, carbohydrates, and fats are all essential dietary nutrients. Nucleic acids (DNA, RNA) are present in food but are not classified as dietary nutrients - they are broken down into their components (nucleotides, bases, sugars) during digestion rather than being absorbed as nutrients.
