In the silver plating of copper. `K[Ag(CN)_(2)]` is used instead of `AgNO_(3)`. The reason is

A

A thin layer of Ag is formed on Cu

B

More voltage is required

C

`Ag^+` ions are completely removed from solution

D

Less availability of `Ag^+` ions, as Cu can not displace Ag from `[Ag(CN)_2]^–` ion
