Vedclass · Answer

(A) The provided structure is Guanine,which is a purine nitrogenous base.In the structure of Guanine,the position labeled '$a$' corresponds to a carbon atom involved in a double bond with oxygen,represented as $(>C=O)$.The position labeled '$b$' corresponds to an amino group attached to the imidazole ring,which is represented as $-NH$ (specifically,the nitrogen atom in the ring structure).Therefore,the correct representation is $a = (>C=O)$ and $b = -NH$.
