The correct option is B The lattice energy of barium sulphate is more than is hydration energy
(a) Correct For greater solubility, hydration energy must be greater than lattice energy.
(b) Correct Greater lattice energy discourage dissolution of a salt.
(c) Incorrect When a salt dissolve, energy is required to break the lattice, which comes from hydration process.
(d) Incorrect Explained in (A).
