-precipitation of a solid from the combination of two liquids

Answer 1

The last one because a change of state is a physical change, ex: melting, freezing, boiling, condensation, vaporization, sublimation and deposition. And if its a physical change it means you could most likely turn it back to its original form. Hope that helps!
