Which one of the following reactions demonstrates that \[{{H}_{2}}{{O}_{2}}\] acts as an oxidising agent in the basic medium?

A) \[N{{a}_{2}}C{{O}_{3}}+{{H}_{2}}{{O}_{2}}\to N{{a}_{2}}{{O}_{2}}+{{H}_{2}}O+C{{O}_{2}}\]

B)  \[2{{\left[ Fe{{\left( CN \right)}_{6}} \right]}^{3-}}+{{H}_{2}}{{O}_{2}}+2O{{H}^{-}}\to 2{{\left[ Fe{{\left( CN \right)}_{6}} \right]}^{4-}}+2{{H}_{2}}O+{{O}_{2}}\]

C)  \[M{{n}^{2+}}+{{H}_{2}}{{O}_{2}}+2O{{H}^{-}}\to Mn{{O}_{2}}+2{{H}_{2}}O\]

D)  \[Mn{{O}_{2}}+{{H}_{2}}{{O}_{2}}+2{{H}^{+}}\to M{{n}^{2+}}+2{{H}_{2}}O+{{O}_{2}}\]
