Homework Answers
adenine is a purine base. purine base structure contains a five membered ring and a six membered ring fused system. so the option c and e only supports this kind of structures and others are not. now between c and e option only e contains three nitrogen at the benzene side .two of them can be hydrogen bonded. on the other hand option c contains three nitrogen and one carbonyl group at the benzene ring side. now the fact is adenine contains nitrogen but no carbonyl group so the structure is option E
