Solution : The correct option is Proteins.
Nitrogen is a necessary component of proteins. Proteins are complex molecules composed of amino acids, with each amino acid including a core carbon atom bound to a variety of functional groups, including an amino group (-NH2) and a carboxyl group (-COOH). The nitrogen atom in the amino group of amino acids is important in the formation of peptide bonds, which connect amino acids to make proteins. A protein's shape and function are determined by its amino acid sequence. In addition to proteins, nitrogen is required for the formation of nucleic acids (DNA and RNA), as well as numerous coenzymes and signalling molecules.
