Phenol is treated with NaOH and then with at 400 K and 4-7 atm, followed by acidification, to give A. A is heated with ethanoic anhydride and a trace of conc. to give B. B is

  1. A4-acetoxybenzoic acid
  2. Bphenyl ethanoate
  3. C2-acetoxybenzoic acid (aspirin)
  4. D2-hydroxybenzoic acid

Answer: C
