(D) The ability to form hydrates depends on the hydration energy of the cation and its size. $MgCl_2$ exists as $MgCl_2 \cdot 6H_2O$. $CaCl_2$ exists as $CaCl_2 \cdot 6H_2O$. $LiCl$ exists as $LiCl \cdot H_2O$. $KCl$ has a large cation size and low hydration energy,so it does not form a hydrate and crystallizes as an anhydrous salt.
