The correct answer is b

Formaldehyde & Acetaldehyde

Reductive ozonolysis 

  • When alkenes/alkynes react with ozone, C=C or C≡C are broken replaced by C=O.
  • For example, when propene reacts with ozone followed by treatment with Zn/H2O, it will form formaldehyde and acetaldehyde.

CH3 - CH = CH2 + O3 →  CH3 - CHO + HCHO
