Answer

A

Explanation

According to Huckel rule for aromaticity the molecule must be planar, cyclic system having delocalised `(4n + 2) pi` electron where nan integer is equal to 0, 1, 2, 3, thus the aromatic compounds have delocalised electron cloud of 2,6,10 or `14pi` electron cyclopropenyl
cations have the `2 pi` electron (n=0) so it is aromatic.
