$\text { The low solubility of LiF and CsI in water is due to }$

• A

  $\text { high lattice enthalpy of LiF and CsI. }$
• B

  $\text { high hydration enthalpy of LiF and CsI. }$
• Correct answer
  C

  $\text { high lattice enthalpy of LiF and low hydration enthalpy of CsI. }$
• D

  $\text { high hydration enthalpy of LiF and low lattice enthalpy of CsI. }$

Hence, the correct answer is option: 'C'.
