Choose the correct option out of the following choices.

Assertion: Olefinic polymers undergo addition polymerization. 

Reason: Polymerization of vinyl chloride is initiated by peroxides/ persulphates.

Assertion and Reason both are correct statement and the reason is not the correct explanation of the  assertion.

Correct reason : 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.
