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*
