We are being asked to determine which statement will increase the voltage/potential for the cell:

Al(s)|Al3+(aq, 1.00 M )||Cu2+(aq,1.00 M)|Cu(s)

In this case, we have to examine each statement and determine which will increase the voltage of the electrolytic cell

I. Increasing the surface area of the Al electrode
