A solution contains `Fe^(2+), Fe^(3+)` and `T^(-)` ions. This solution was treated with iodine at `35^(@)C. E^(@)` for `Fe^(3+), Fe^(2+)` is `0.77 V` and `E^(@)` for `I_(2)//2I^(-)` = 0.536 V. The favourable redox reaction is:

A

`I_2` will be reduced to `I^-`

B

There will be no redox reaction

C

`I^-` will be oxidised to `I_2`

D

`Fe^(2+)` will be oxidised to `Fe^(3+)`
