An aqueous solution containing Na^(+),Sn...

An aqueous solution containing `Na^(+),Sn^(2+),Cl^(-)` & `SO_(4)^(2-)` ions, all at unit concentration is electrolysed between a silver anode and a platium cathode. What changes occur at the electrodes when curret is passed through the cell? Given `E_(Ag^(+)|Ag)^(0)=0.799V`,
`E_(Sn^(2+)|Cn)^(0)=-0.14V,E_(Cl_(2)|Cr^(-))^(0)=1.36V,E_(S_(2)O_(8)^(2-)|SO_(4)^(2-))=2V,E_(Sn^(4+)|Sn^(2+))^(0)=0.13V`
(A). `Sn^(2+)` is reduced and `Cl^(-)` is oxidized
(B). Ag is oxidized and `Sn^(2+)` is reduced
(C). `Sn^(2+)` is reduced and `Sn^(2+)` is oxidized
(D). `H^(+)` is reduced and `Sn^(2+)` is oxidised
