The free energy change of dissolving must be positive. D. The energy required to break bonds apart must be greater than the energy released from the substance reacting with the solvent.

I think either A. or B. As a would be always true as dissolving and solid will always increase the entropy. I am thinking it may be B because for all kinds of reaction if the DeltaH and DeltaS combine to be favorable negative Delta G/Free energy then the substance will dissolve.
As A would be always true as dissolving any solid will always increase entropy*
