Solution
The correct option is C
Answer : (a)
For a compound to be aromatic it should be cyclic, planar and should have conjugated pi−bond. It should also obey 4n+2 rule.
Compound (a) has 6π− electron and obeys all the condition. Hence, it is a aromatic compound.
Compound (b) and (c) are non-aromatic because it is not planar. It has a sp3 hybridised carbon.
Compound (d) is antiaromatic since it has 4 pi− electrons.
