(c) Cations move toward copper electrode.
Explanation:
Daniel cell is an electrochemical cell in which Cu acts as cathode and Zn acts as an anode.
In Daniel cell,
(i) Electrons flow from Zn (anode) to Cu (cathode).
(ii) Current flows from Cu (cathode) to Zn (anode).
(iii) Cu2+ ions (cations) move towards Cu (cathode) and accumulated as Cu metal.
