Hydrogen peroxide oxidises [Fe(CN)(6)]^(...

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+O_(2))`

B

`H_(2)O and (H_(2)O+OH^(-))`

C

`(H_(2)O+O_(2))` and `H_(2)O`

D

`(H_(2)O+O_(2))` and `(H_(2)O+ OH^(-))`
