1. Homework Statement :
please refer to the picture attached


Homework Equations

: [/B]A compound is aromatic if it is planar and it satisfies Huckles 4n+2 Π electron rule.


The Attempt at a Solution

: [/B]
Option A is not correct...I dont know why...just speaking from intuition..probably its not planar due to angular strain..I dont know..
Option B is also not correct because we have 8Π electrons which makes it anti aromatic.
Option C also is incorrect as we have 12 Πelectrons making it antiaromatic.
Same is true for Option D.
Then which one is correct? Is it option A as it is the only option I discarded based on intuition.

Where are the unhybridized p orbitals in that molecule?
