Which one of the following reactions represents the oxidizing property of H2O2 ?

⇒In the above reaction H2O2 reduces the Mn+7 to Mn+2 there H2O2 acts as reducing agent.⇒ In the above reaction H2O2 acts as a reducing agent since it reducing agent Fe+3 [ferric] to Fe+2 [ferrous].⇒In the above reaction H2O2 acts as a reducing agent since it reducing agent Pb+4  to Pb+2⇒In the above reaction H2O2 acts as  oxidising agent,since it oxidises the   I-1 to I2
