(B) In fused $CaH_2$,the dissociation occurs as: $CaH_2(l) \rightarrow Ca^{2+} + 2H^-$. At the cathode,the reduction of $Ca^{2+}$ ions occurs: $Ca^{2+} + 2e^- \rightarrow Ca$. At the anode,the oxidation of hydride ions $(H^-)$ occurs: $2H^- \rightarrow H_2(g) + 2e^-$. Therefore,hydrogen gas is produced at the anode.
