Observe the following statements:
Statement-$I$: Both $LiF$ and $CsI$ have low solubility in water.
Statement-$II$: Low solubility of $LiF$ in water is due to its high lattice enthalpy,and that of $CsI$ is due to its smaller hydration enthalpy of ions.

• A
  Both statements $I$ and $II$ are correct
• B
  Statement $I$ is correct,but statement $II$ is not correct
• C
  Statement $I$ is not correct,but statement $II$ is correct
• D
