${\text{MnO}}_4^{-}+8{\text{H}}^{+}+5{\text{e}}^{-}\to {\text{Mn}}^{2+}+4{\text{H}}_2\text{O}$
${\text{H}}_2{\text{O}}_2 \to {\text{O}}_2+2{\text{H}}^{+}+2{\text{e}}^{-}$
${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$acts as reducing agent gets oxidised
${\text{H}}_2{\text{O}}_2\stackrel{{\text{K}}_2{\text{Cr}}_2{\text{O}}_7}{\to }{\text{CrO}}_5$
${\text{CrO}}_{\text{5}}$formation possibility is there, so${\text{K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$not selected as choice but${\text{KMnO}}_{\text{4}}$selected.
