Quizplus · Accepted Answer

The region of a copolymer can be determined based on its monomer composition. Isobutylene and vinyl fluoride are two different monomers.

Regions I, II, and IV do not have the combination of both monomers, so they cannot be the region of this copolymer. Therefore, the answer is C.
