The correct answer is: **The temperature remains constant and the heat energy is increasing during a phase change.**
During a phase change, such as melting or boiling, the temperature of the substance does not change; instead, heat energy is added or removed to facilitate the change of state (from solid to liquid, or from liquid to gas, for example).
