The Correct Option is C
Solution and Explanation
Step 1: Understanding essential elements.
Plants require several chemical elements for growth and development. These are categorized into:
- Macronutrients: N, P, K, Ca, Mg, S (6)
- Micronutrients: Fe, Mn, Zn, Cu, Mo, B, Cl, Ni (10)
Step 2: Count of essential elements.
- Total number of essential elements for normal plant growth = 16 (6 macro + 10 micro).
Step 3: Conclusion.
Hence, 16 essential elements are required by plants for normal growth.
