Which option correctly pairs a macronutrient example with a micronutrient example?

Explanation:
In plant nutrition, macronutrients are required in much larger amounts than micronutrients. Nitrogen fits as a macronutrient because plants need it in relatively large quantities to build amino acids, proteins, and chlorophyll. Iron, on the other hand, is a micronutrient needed only in trace amounts but is essential for key catalytic roles in electron transport and enzyme function. So pairing nitrogen with iron correctly shows a macronutrient example with a micronutrient example.
