On the bassis of standard electrode potential of redox couples given below, find out which of the following is the strongest oxdising afent .
`(E^@ value : Fe^(3+)) = + 0. 77 C, I_(2(g)) | I = + 0/ 54 V`,
`Cu^(2+) | Cu = + 34 V, Ag^(+) |Ag = + 0. 80 V)`.
A. ` Fe^(3+)`
B. ` I_2(g)`
C. ` Cu^(2+) `
D. `Ag^+`
