Correct Answer: Nitrogen
Solution : The correct option is Nitrogen.
Nitrogen is a necessary element that plants may take in both cation (positively charged) and anion (negatively charged) forms. Plants may absorb ammonium ions (NH4+) from the soil in their cationic form, but not nitrate ions (NO3-) in their anionic form. These nitrogen types are essential nutrients for plant growth and development.
