(C) The reaction is an intramolecular benzoin condensation followed by rearrangement. $CN^-$ acts as a nucleophile and attacks the aldehyde carbonyl group. This is followed by an intramolecular attack on the ketone carbonyl group. After hydrolysis and rearrangement,the final product $E$ is formed,which is a cyclic compound as shown in the reaction mechanism.
