Solution

The correct option is C ${[C o {(e n)}_{2} C l_{2}]}_{2}^{+}$
The complex ${[C o {(e n)}_{2} C l_{2}]}_{2}^{+}$ shows geometrical isomerism. It exists in the form of cis and trans isomers. The cis isomer is optically acitve and exists in the form of d and l isomers. The trans isomer is optically inactive.
