(C) The given species is the cyclopentadienyl anion $(C_5H_5^-)$.It contains two double bonds,which contribute $2 	imes 2 = 4$ $\pi$ electrons.The negative charge on the carbon atom is part of the conjugated system,contributing an additional $2$ $\pi$ electrons.Total $\pi$ electrons = $4 + 2 = 6$ $\pi$ electrons.This species follows $H$ückel's rule ($4n + 2$ $\pi$ electrons,where $n=1$) and is aromatic.

How many $\pi$ electrons are there in the following species:
