Polymerisation of three $C_2H_2$ molecules

(C) The correct answer is $(C)$.Benzene is obtained by the cyclic polymerization of three molecules of acetylene $(C_2H_2)$ when passed through a red-hot iron or copper tube at $500\ ^oC$.The reaction is as follows:$3CH \equiv CH \xrightarrow{\text{Red hot } Cu/Fe, 500\ ^oC} C_6H_6$
