Solution

The correct option is C $A u$
Impure silver sheets are used as an anode and thin sheets of pure silver are used as the cathode. As electric current is passed through the electrolyte, the anode gradually dissolves and pure silver is deposited on the cathode.
Impurities like $Z n$ and $C u$ go into the solution while gold ( $A u$ ) settles down at the anode as anode mud.
