Hydrogen peroxide oxidises `[Fe(CN)_(6)]^(4-)` to `[Fe(CN)_(6)]^(3-)` in acidic medium but reduces `[Fe(CN)_(6)]^(3-)` to `[Fe(CN)_(6)]^(4-)` in alkaline medium. The other products formed are, respectively
A. `H_(2)O" and "(H_(2)O+OH^(-))`
B. `(H_(2)O+O_(2)) " and "H_(2)O`
C. `(H_(2)O+O_(2))" and "(H_(2)O+OH^(-)`
D. `H_(2)O" and "(H_(2)O+O_(2))`
