Relation between solubility and temperature

The plot of solubility of some salts against temperature is given on the right. A salt like $\ce{NaCl}$ can be recovered fully, when dissolved in a solvent and the solvent is removed by evaporation. Choose the correct statement(s).

enter image description here

(A) No heat is absorbed or released when $NaCl$ is dissolved in water.

(B) More heat is released when the ions of $Yb_2(SO_4)_3$ are solvated than that absorbed when the ions are separated.

(C) The heat of solution is negative for $H_3BO_3$.

(D) When $AlCl_3$ is dissolved in water and the water is evaporated, solid $AlCl_3$ is recovered.

My approach: (A) is clearly correct. (C)&(D) are clearly wrong. My confusion lies with (B).
