When a solution of `AgNO_3` (1 M) is electrolysed using platinum anode and copper cathode, what are the products obtained at two electrodes?
Given :`E_(cu^(2+)|cu)^(@)=+0.34 "volt", E_(O_2,H^+|H_2O)^(@)=+1.23"volt",E_(H^+|H_2)^(@)=+0.0"volt" E_(ag^+|Ag)^(@)=+0.8 "volt"`
A. `CutoCu^(2+)` at anode, `Ag^+to Ag` at cathode
B. `H_2OtoO_2` at anode, `Cu^(2+)to Cu` at cathode
C. `H_2OtoO_2` at anode, `Ag^+to Ag` at cathode
D. `NO_3^-to NO_2` at anode, `Ag^+to Ag` at cathode
