Explanation:

Solubility is a fundamental concept in chemistry. It specifically refers to the ability of a solute (a substance) to dissolve in a solvent. Option A describes conductivity, which is about the flow of electric current. Option B is about a physical change in color, not related to dissolving. Option D is about melting, a phase - change related to temperature. Only option C correctly defines solubility as the ability of a substance to dissolve in a solvent.
