Neoprene rubber is prepared by free radical polymerisation of chloroprene (2-chlorobuta-1, 3-diene),The chloroprene is obtained by dimerisation of acetylene by passing it through aqueous solution of $NH_4Cl$ and cuprous chloride at 343K followed by treatment with HCl.
Hence (b) is the correct answer.
