(C) Essential mineral elements are those that are absolutely necessary for the growth,development,and reproduction of plants. According to the criteria of essentiality,$17$ elements are considered essential for plants. These include Macronutrients (e.g.,$C, H, O, N, P, K, Ca, Mg, S$) and Micronutrients (e.g.,$Fe, Mn, Cu, Zn, B, Mo, Cl, Ni$). Iron $(Fe)$,Manganese $(Mn)$,and Phosphorus $(P)$ are all essential elements for plant metabolism and growth. Cadmium $(Cd)$ is a heavy metal that is not required by plants and is often toxic to them even in small concentrations. Therefore,Cadmium is not an essential mineral element.
