(C) Plants require mineral elements in varying amounts. Based on their quantitative requirements, they are divided into two categories: macronutrients and micronutrients.Macronutrients are generally present in plant tissues in large amounts (in excess of $10 	ext{ mmol kg}^{-1}$ of dry matter). Examples include Carbon, Hydrogen, Oxygen, Nitrogen $(N)$, Phosphorus $(P)$, Potassium $(K)$, Calcium $(Ca)$, Magnesium $(Mg)$, and Sulphur $(S)$.Micronutrients or trace elements are needed in very small amounts (less than $10 	ext{ mmol kg}^{-1}$ of dry matter). Examples include Iron $(Fe)$, Manganese $(Mn)$, Copper $(Cu)$, Molybdenum $(Mo)$, Zinc $(Zn)$, Boron $(B)$, Chlorine $(Cl)$, and Nickel $(Ni)$.Therefore, among the given options, $Mn$ (Manganese) is a micronutrient, while $P$, $Ca$, and $N$ are macronutrients.
