The correct option is B Hydration Energy > Lattice energy
Hydration energy is the energy released when ions are dissolved in water i.e., negative in magnitude.
Lattice Energy is energy required to break the bond between the oppositely charged ions i.e., positive in magnitude.
Enthalpy of solution=Lattice energy+Hydration energy
So, the dissolution of a solute is exothermic only when Hydration Energy>Lattice Energy.
