For the galvanic cell
\( \mathrm{Zn}\left|\mathrm{Zn}^{2+}(0.1 \mathrm{M}) \| \mathrm{Cu}^{2+}(1.0 \mathrm{M})\right| \mathrm{Cu} \) the cell potential increase if:
(a) \( \left[\mathrm{Zn}^{2+}\right] \) is increased
(b) \( \left[\mathrm{Cu}^{2+}\right] \) is increased
(c) \( \left[\mathrm{Cu}^{2+}\right] \) is decreased
(d) surface area of anode is increased
