\( \mathrm{H}_{2} \mathrm{O}_{2} \) acts as a reducing agent in
(A) \( 2+\mathrm{HCl}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{FeCl}_{3}+\mathrm{H}_{2} \mathrm{O} \)
(B) \( \mathrm{Cl}_{2}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{HCl}+\mathrm{O}_{2} \)
(C) \( 2 \mathrm{HI}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{I}_{2}+\mathrm{H}_{2} \mathrm{O} \)
(D) \( \mathrm{H}_{2} \mathrm{SO}_{3}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{H}_{2} \mathrm{SO}_{4}+\mathrm{H}_{2} \mathrm{O} \)
