The phase change from gas to solid is...

Explanation:
When a gas becomes a solid, the process is deposition, and the molecules release energy as they settle into a solid structure. That energy is given off to the surroundings, so this transition is exothermic. The other terms describe heat flow conditions (isothermal vs adiabatic) rather than the direction of energy change, and endothermic would mean heat is absorbed, which isn’t happening here.
