Correct answer and explanation

Correct answer: Nitrogen

Explanation: āœ… Correct Answer: C. Nitrogen šŸ“š Explanation: Pure sugar, chemically known as sucrose, is a carbohydrate with the molecular formula $\text{C}_{12}\text{H}_{22}\text{O}_{11}$. This structure confirms that it is composed entirely of carbon, hydrogen, and oxygen atoms. Therefore, 'Nitrogen' is completely absent from pure sugar. Nitrogen is typically found in proteins and amino acids rather than simple plant carbohydrates.
