(A) $(i)$. In Downs cell,the electrolyte used is a fused mixture of $40\% NaCl$ and $60\% CaCl_2$ to lower the melting point.$(ii)$. In the Dow sea water process,magnesium is extracted from sea water,and the electrolyte used is fused $MgCl_2$.$(iii)$. In the Hall-Heroult process,the electrolyte used is a fused mixture of $Al_2O_3$ and $Na_3AlF_6$ (cryolite).$(iv)$. In the Moissan process,the electrolyte used is fused $KHF_2$ for the preparation of fluorine.Therefore,the correct match is $(i-Z, ii-W, iii-X, iv-Y)$.

$(I)$ (process)	$(II)$ (electrolyte)
$(i)$. Downs cell	$(W)$. fused $MgCl_2$
$(ii)$. Dow sea water process	$(X)$. fused $(Al_2O_3 + Na_3AlF_6)$
$(iii)$. Hall-Heroult	$(Y)$. fused $KHF_2$
$(iv)$. Moissan	$(Z)$. fused $(40\% NaCl + 60\% CaCl_2)$
