Determine whether the molecule shown below is aromatic, antiaromatic, or nonaromatic. If it is aromatic, calculate its n from Hückel's rule. If not, explain how it violates the aromaticity requirements.

The molecule is nonaromatic. It violates all the Huckel's rule.

The molecule is antiaromatic. It is cyclic, planar and conjugated, but it has 4n+2 electrons.

The molecule is antiaromatic. It is cyclic, planar and conjugated, but it has 4n electrons.

The molecule is aromatic. Its n is 1.
