Solution

The correct option is B With the positive terminal
In order to deposit the copper on the iron spoon, Cu2+ present in the solution should deposit to iron spoon and we know that Cu2+ will move toward negative terminal as it is positively charged. So the iron spoon is to be connected with negative terminal and Copper plate is to be connected with positive terminal.
Therefore, B is correct option.
