Reduction occurs at $Cu$ which acts as the cathode.

(B) In a $Cu-Zn$ cell (Daniell cell),the electrode reactions are as follows:At the anode $(Zn)$: $Zn(s) \rightarrow Zn^{2+}(aq) + 2e^-$ (Oxidation)At the cathode $(Cu)$: $Cu^{2+}(aq) + 2e^- \rightarrow Cu(s)$ (Reduction)Therefore,reduction occurs at the $Cu$ electrode,which acts as the cathode.
