Solution

The correct option is A neoprene

Ziegler–Natta catalysts are used to polymerize terminal alkenes (ethylene and alkenes with the vinyl double bond)

AlR3 and TiCl4 are used as Ziegler–Natta catalyst.

CH2=CClCH=CH2 is a terminal alkene. On treatment with Ziegler-Natta catalyst it gives neoprene.
Hence, the correct answer is A.
