(A) Essential mineral elements are classified into two categories based on their quantitative requirements: macro-nutrients and micro-nutrients.Macro-nutrients 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,Phosphorus,Sulphur,Potassium,Calcium,and Magnesium.Micro-nutrients or trace elements are needed in very small amounts (less than $10 	ext{ mmol kg}^{-1}$ of dry matter). Examples include Iron,Manganese,Copper,Molybdenum,Zinc,Boron,Chlorine,and Nickel.Among the given options,Copper $(Cu)$ is a micro-element,while Calcium,Magnesium,and Oxygen are macro-elements.
