Compounds A, B, and D are all examples of aromatic compounds, meeting the requirements of having a cyclic structure, planarity, and a Huckel's rule compliant pi electron system. In contrast, compound C does not possess a Huckel's rule compliant pi electron system, as it has only 4 pi electrons rather than the required 4n+2. Therefore, it is considered non-aromatic.
