○ does not include proteins or nucleic acids
○ includes proteins
○ could only be made of carbohydrates

Explanation:

Proteins have nitrogen (and sometimes sulfur), nucleic acids have nitrogen and phosphorus. The food has only C, O, H, so it can’t have proteins or nucleic acids. Carbohydrates (C, H, O) and triglycerides (C, H, O) are possible, but “only” in other options is wrong.

A. Does not include proteins or nucleic acids
