    option D. here sp3 carbon is present and also conjunction in whole ring is not possible so molecule is non planar and non aromatic. To be aromatic, molecule must have planar, cyclic and conjugate system having 4n+2 pi electrons system

    Option D is non aromatic...No complete conjugation. If electron doesn't delocalise then compound is non aromatic.If electron delocalise then on basis of huckel rule you can identify for aromatic and antiaromatic.
