Which of the following equation depicts the oxidizing nature of H _...

Oxidizing nature of H₂​O₂​ means it oxidizes other substance and itself gets reduced. In such reactions O₂​ is not evolved.

$2{I}^{-} + {H}_{2}{O}_{2} + 2{H}^{+} \to {I}_{2} + 2{H}_{2}O$

Oxygen reduces from $- 1$ to$- 2$

So, its reduction will takes place. Hence it will behave as oxidising agent or it shows oxidising nature. While in other option it change from $( - 1 )$ to $0$.
