Correct option is B
The boiling point of H2O2 cannot be determined experimentally by distillation.As it undergoes decomposition below its boiling point as H2O and O2 .Due to presence of weak peroxy bond it undergoes decomposition.H2O2 → H2O + 1/2O2Because of this reason H2O2 is purified from its aqueous solution by distillation under reduced pressure Statement I is true and statement II is false.
