Why is fluorine's high electronegativity significant in the formation of compounds like Teflon (polytetrafluoroethylene)?

Fluorine's high electronegativity leads to weak bonds with carbon, making Teflon highly stable.

Fluorine's high electronegativity makes Teflon highly unreactive but unstable.

Fluorine's high electronegativity makes Teflon highly reactive and unstable.

Fluorine's high electronegativity leads to strong bonds with carbon, making Teflon highly stable and non-reactive.
