Select the correct statement if-
`E_(Mg^(2+)//Mg)^(@)=-2.4V, E_(Sn^(4+)//Sn^(2+))^(@)=0.1V, E_(MnO_(4)^(-),H^+//Mn^(2+))^(@)=1.5V, E_(I_(2)//I^(-))^(@)=0.5V`

A

`MnO_(4)^(-)` is the strongest oxidizing agent and Mg is the strongest reducing agent.

B

`Sn^(4+)+2I^(-)toSn^(2+)+I_(2)` is a spontaneous reaction.

C

`Mg^(2+)+Sn^(2+)toMg+Sn^(4+)` is a spontaneous reaction.

D

Here, weakest oxidizing agent is `Sn^(4+)` and weakest reducing agent is `Mn^(2+)`
