Solution
The correct option is D Mn, Zn & Cu
Micronutrients or trace elements are those essential elements which are required by plants in small amounts, less than 10 mmol/kg of dry matter. Hence the concentration when it exceeds 10 mmol/Kg of dry matter in plants may result in toxicity. Mn, Cu, Mo, Zn, B, Cl and Ni are the micronutrients whereas C, H, O, N, P, K, Ca, Mg, S are macronutrients .
