Options

  1. AEthylene glycol and phthalic acid
  2. BCaprolactum and 1, 3-butadiene
  3. CPhenol and formaldehyde
  4. D3-hydroxybutanoic acid and 3-hydroxypentanoic acid

Correct answer

D. 3-hydroxybutanoic acid and 3-hydroxypentanoic acid

Step-by-step solution

PHBV is a biodegradable polymer that belongs to the family of polyhydroxyalkanoates (PHAs). It is composed of two monomeric units i.e. 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.
