e) CF2=CF2
Polymerization of tetrafluoroethylene is used to prepare polytetrafluoroethylene (PTFE) polymers such as Teflon. PTFE is one of the three fluorocarbon resins composed wholly of fluorine and carbon. The other resins in this group are perfluoroalkoxy resin (PFA) and fluorinated ethylene propylene (FEP). TFE is also used in the preparation of copolymers such as ETFE.

Look at the balance of the reaction- ask yourself what would keep the ratio of carbon and fluorine the same?
Remember, also, what is happening. The reactive bit at the end of the still growing polymer chain is attaching to a monomer- it opens a double bond.
So, I'll be more explicit- e. e is the answer!
