Given that
`E_(Ni^(2+)//Ni)^(@)=-0.25V, E_(Cu^(2+)//Cu)^(@)=+0.34V`,
`E_(Ag^(+)//Ag)^(@)=+0.80V , E_(Zn^(2+)//Zn^(-))=-0.76V`.
Which of the following redox processes will not take place in specified direction ?

A

If `E_("ext") gt 1.1V, e^(-)` flows from , Cu to Zn

B

If `E_("ext") gt 1.1V, Zn` dissolves at Zn electrode and Cu deposits at Cu electrode

C

If `E_("ext") lt 1.1V, Zn` dissolves at anode and Cu deposits at cathode

D

If `E_("ext")` = 1.1 V , no flow of `e^(-)` or current occurs
