$H_2O_2 + 2OH^- \rightarrow O_2 + 2H_2O + 2e^-$

(D) reducing agent is a substance that undergoes oxidation by losing electrons.In the reaction $H_2O_2 + 2OH^- \rightarrow O_2 + 2H_2O + 2e^-$,the oxidation state of oxygen in $H_2O_2$ increases from $-1$ to $0$ in $O_2$.Since $H_2O_2$ loses electrons and is oxidized,it acts as a reducing agent.
