C Correct answer
Explanation

A large number of polymers are quite resistant to 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, orthopaedic 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.
