(D) The correct option is $(d)$.Among the given salts,$CaCl_2$,$LiCl$,and $BaCl_2$ have the ability to form hydrates such as $CaCl_2 \cdot 6H_2O$,$LiCl \cdot 2H_2O$,and $BaCl_2 \cdot 2H_2O$.This is due to the relatively higher hydration enthalpies of $Ca^{2+}$,$Li^{+}$,and $Ba^{2+}$ ions compared to $Na^{+}$ and $K^{+}$.$NaCl$ and $KCl$ do not form hydrates under normal conditions.
