Solution

The correct option is D these molecules have exceptionally high attractive forces in their lattice
A number of ionic compounds, e.g $A g C l, C a F_{2}, B a {S O}_{4}$ are insoluble in water. This is because these molecules have exceptionally high attractive forces in their lattice. Ionic compounds having lattice energy higher than hydration energy are insoluble in water. Ionic compounds having lattice energy lesser than hydration energy are soluble in water.
