Answer:
The nutrients that provide 9 calories per gram consumed are fats (option D).

Lipids and fats are biomolecules, considered as macronutrients of high energy value. These compounds are necessary for body composition, participate in biological processes and be a source of reserve energy.
The energy value of fats is high, since they provide 9 calories for every gram consumed, unlike other nutrients.
The other options are not correct because:
Carbohydrates and proteins provide 4 calories per gram consumed.
