(D) Nitrogen is an essential nutrient for plants as it is a major component of proteins,nucleic acids,vitamins,and hormones.In plants,nitrogen is required by all parts,but it is particularly essential for the meristematic tissues (which are actively dividing) and the metabolically active cells (which require high amounts of proteins and enzymes for chemical reactions).Therefore,both $I$ and $IV$ are the primary sites of nitrogen requirement.
