C Correct answer
Explanation

A large number of polymers are quite resistant to the environmental degradation processes, and are thus responsible for the accumulation of polymeric solid waste materials. It is obtained by the copolymerisation of 3-hydroxybutanoic acid and 3 - hydroxypentanoic acid. PHBV is used in speciality packaging, orthopedic devices and in controlled release of drugs. PHBV undergoes bacterial degradation in the environment. The examples of non-biodegradable polymers are- PMMA (poly methyl methacrylate), PVC (polyvinyl chloride), PVAc (polyvinyl acetate), PFR (phenol formaldehyde resin), PP (polypropylene), etc.
