As we learnt in

Chemical Cells -

The cells in which electrical energy is produced from the energy change accompanying a chemical reactions or a physical process are known as chemical cells.

-

 

 

One cell cannot be used in this case because two electrodes of the same substance in a single electrolyte will have no potential difference.

\therefore Solution\, \, is\, \, 1
