JEE Main Chemistry question

The hydration of ionic compounds involves:

(A)Evolution of heat
(B)Weakening of attractive forces
(C)Dissociation into ions
(D)All of the aboveCorrect

Answer: (D)

Solution

When an ionic solid dissolves/hydrates in water, the lattice breaks apart into free ions (dissociation), the ion-ion attractive forces are replaced/weakened by weaker ion-dipole interactions with water, and the
