Which of the following statements best describe the melting point?

Out of the following statements, the best statement which describes the melting point : Kinetic energy remains constant and potential energy increases.

The substance's melting point is defined as the temperature at which the solid-state changes to the liquid state. At the melting point, ice absorbs heat, increasing its potential energy. However, kinetic energy remains constant till all water in the solid phase(ice) is transformed into the water in the liquid phase.
