Correct Option - 4
Detailed Solution:
(1) Standard enthalpy of formation for alkali metal bromides becomes more negative on descending down the group.
(2) Standard enthalpy of formation for LiF is most negative among alkali metal fluorides.
(3) In case of Csl, lattice energy is less but Cs+ having less hydration energy due to which it

Li+ has the highest hydration enthalpy.
Hence it is most hydrated
Therefore, Correct order of hydrated radii is Cs+ < Rb+ < K+ < Na+ < Li+
