Solution

The correct option is D All the above
We have just seen that addition polymerization happens through the free radical mechanism or the ionic mechanism.

In the free radical mechanism, we have seen that polymerisation starts with the help of a free radical initiator. This can either be a peroxide initiator which spontaneouly gives us free radicals, or it could also be a radiated halogen species which we have learnt about in the alkanes chapter.
