Which from following is a non benzenoid aromatic compound?

Non-benzenoid aromatic compounds satisfy Hückel's rule while lacking a benzene ring structure.

Aniline contains a benzene ring, making it benzenoid aromatic.

Naphthalene consists of fused benzene rings, classifying it as benzenoid aromatic.

Phenol features a benzene ring substituent, rendering it benzenoid aromatic.

Tropone forms a seven-membered cycloheptatrienone ring with $6\pi$ electrons satisfying Hückel's rule ($4n + 2$ where $n = 1$), establishing it as non-benzenoid aromatic.

The non-benzenoid aromatic compound is therefore $\boxed{B}$.
