Select the eight compounds below that are expected to exhibit aromatic stabilization. Note that lone pairs have not been shown - their presence or absence has to be inferred from the number of bonds and the formal charge (if any). Assume that the system can achieve planarity if needed for aromaticity. Note - higher partial credit could be achieved by selecting less than eight of them if you are unsure on some of them.
