The correct conclusion is:
**C. The liquid formed from a melted solid has the same mass as the solid has.**
This conclusion is based on the principle of conservation of mass, which states that mass is neither created nor destroyed in a closed system. When the ice melts in the sealed container, it transforms from solid to liquid, but the total mass of the container, its lid, and its contents will remain the same before and after the melting process.
