Deposition is the phase change from gas to solid.

Explanation:
Deposition is the direct change from a gas to a solid, skipping the liquid phase. This occurs when gas molecules lose enough energy to arrange themselves into a solid lattice, often seen as frost forming on a very cold surface. The other processes involve gas turning into liquid (condensation), liquid turning into gas (vaporization), or solid turning into gas (sublimation), none of which describe deposition. So the gas-to-solid description is the correct one.
