Solution

Answer: (a). Assertion and reason both are correct but reason does not explain assertion.

Correct reason (R): Olefins like ethene undergo addition polymerization to give polymer like polythene.

Olefin monomers undergo addition polymerization because it adds on to other monomers of olefin through free radical mechanism due to the presence of peroxide initiator and double bond and products high molecular mass polymers.
