As we move down the group, size of metal increases. Be has lower size while

SO_{4}^{2 -}

has bigger size, that's why

BeSO_{4}

breaks easily and lattice energy becomes smaller but due to lower size of Be, water molecules are gathered around and hence hydration energy increases. On the other hand, rest metals i.e.

Ca, Ba

, Sr have bigger size and that's why lattice energy is greater than hydration energy. Smaller sized atom has more hydration energy. Thus, in this question Be is placed upper most in the group has lesser size and not comparable with the size of sulphates. Hence,

BeSO_{4}

is the right response.
