Answer:

The most correct option is carbohydrates & lipids

Explanation:

Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.

Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, <em>proteins have a large number of nitrogen atoms thus not part of the answer.</em>

<em>Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.</em>
