In the Ag Fe cell Ag works as cathode while Fe is anode see image for solution
in comparison to hydrogen electrode reduction potential of Co cell is negative it means it does not want to reduce itself rather it want to oxidise itself so it will give electron and work as anode so it works as anode in comparison to hydrogen electrode oxidation occurs here wnd option is correct
