Correct answer and explanation

Correct answer: NaNO3

Explanation: āœ… Correct Answer: D) NaNO3 šŸ“š Explanation: Sodium Nitrate ($\text{NaNO}_3$), commonly known as Chile saltpeter, is a chemical compound widely used as a nitrogen-based fertilizer in agriculture. It supplies essential nitrogen nutrients directly to plants to promote healthy growth and crop yield. Pure elemental substances like $\text{N}_2$ gas or $\text{O}_2$ cannot be used directly by plants as fertilizers. This compound dissolves easily in soil water, making it readily available for root absorption.
