Which of the following alkaline earth metal sulphates has hydration enthalpy higher than the lattice enthalpy?

As hydration energy decreases solubility decreasesIf anion size is large   SO4-2,CO3_2   then with small change in cation size there is no considerable change in lattice energy then the solubility depends on the hydration energy i.e., here hydration energy dominating factor over lattice energyWith increase in size of cation hydration energy decreases and hence solubility decrerases.Hydration energy α SolubilityBeSO4 readily soluble in waterWhere as as BaSO4 is least soluble in water
