Solution

The correct option is A Fe, Zn, B, Cl and Ni
Based on their quantitative requirements, plant nutrients are divided into:

(i) Macronutrients: They are generally present in large amounts (more than 10 mmole/kg of dry matter).
Examples: C, H, O, N, P, S, K, Ca and Mg.

(ii) Micronutrients: They are needed in very small amount (less than 10 mmole/kg of dry matter).
Examples: Fe, Mn, Cu, Mo, Zn, B, Cl and Ni.
