Reason ; Among the listed options , the carbs are not the polymer to amino acids or does't have any relation with these amino acids. It ratio of hydrogen to oxygen is not more than 2:1 but is same as the value. therefore the above given option would be the appropriate match for the carbs.
2). Protein ; Answer - B) Polymers of amino acids
Reason ; Among the listed option, the above mentioned description would be the most suitable one, cause there is always a strong relationship between the protein and amino acids, and the statement about the polymer of amino acids regarding protein would be the actual fact.
3. Lipids ; Answer - A) Contain a high ratio of hydrogen to oxygen.
Reason ; When comparing to carbs, the above mentioned lipid has higher ratio in regard to the hydrogen to the oxygen, Therefore the above mentioned option would be the appropriate match for the lipids molecule
