In a hydraulic cylinder where the rod diameter is equal to one half the piston's diameter, what is the difference in load-carrying capacity between extension and retraction if the pressure is constant?

a) The load-carrying capacity is the same in both extension and retraction.
b) The load-carrying capacity is higher during extension.
c) The load-carrying capacity is higher during retraction.
d) The load-carrying capacity cannot be determined from the given information.
