Which three elements are needed for the healthy growth of plants:
Correct answer: C. N, P, K
- A. N, S, P
- B. N, Ca, P
- C. N, P, K
- D. N, K, C
Explanation
Option C (N, P, K) is correct because it includes nitrogen, phosphorus, and potassium, which are essential nutrients for healthy plant growth. Nitrogen is needed for protein, enzyme, and chlorophyll formation. Phosphorus is crucial for energy transfer, root development, and flower and fruit formation. Potassium helps regulate water uptake, enhance photosynthesis, and improve disease resistance. Together, these elements support plant growth and maximize yields.
