Vedclass · Answer

(D) The given structure represents a pyrimidine ring with two carbonyl groups at positions $2$ and $4$. This specific structure is characteristic of Uracil. Thymine is $5$-methyluracil,which would have a methyl group at the $5$th position. Cytosine has an amino group at the $4$th position instead of a carbonyl group. Adenine is a purine,which consists of a double-ring structure. Therefore,the correct option is $D$.
