the anode is a silver rod and the cathode is the spoon
the anode is the spoon and the cathode is a silver rod
the electrolyte is silver trioxonitrate(v)( solution and the cathode is a silver rod.
the electrolyte is silver trioxonitrate(v) solution and the anode is the spoon

Explanatory...so...The steel spoon to be coated with silver is the cathode of the electrolytic cell. The anode of the electrolytic cell is made of a silver metal and the electrolyte used for electroplating silver on spoon must contain silver ions (Ag + ) , for example, silver nitrate (AgNO3) or silver cyanide (AgCN) dissolved in water.
the arrangement of the electrolytic cell is the same as that used in the electrolysis, the pure metal is rhe cathode whole the impure metal which is to be separated is the anode , for example copper is an electro positive metal that is below hydrogen in the electrochemical series and recall that the metals that are above hydrogen are separated by electrolysis of its ores , because they existrd in their natural ores while metals that are below hydrogen exist in their uncombined state
now the impure copper metal receive two electrons to go into solution, while the pure copper ion are attracted to the cathode where they receive two electrons to be neutral snd they are later discharged as neutral atom, so in the electroplating of a metal by another metal the metallic object to be electroplated is made of the cathode while the strip of te plating metal is the anode , since spoon is to ne electroplated by silver it is made od the cathode , while silver which is the electroplating strip is made of the anode
so option A is correct
oxidation takes place at the anode while reduction takes place at the cathode
since the spoon is to be coated it should be at the anode so as to be oxidized by the silver at the cathode
So, Spoon is had to be placed as Cathode. Confusion happens in considering anode and cathode and its connection with the battery. It is important to remember that anode is connected to positive terminal of battery and cathode to negative terminal.
I rest my case👀
