letter D. Potential energy increases, and kinetic energy stays the same

Endothermic Processes - Heat flows into the system from the surroundings. The products are at higher energy than the reactants, as they have absorbed this energy.

The correct option is D.

An endothermic reaction is a type of reaction that absorb energy from the environment, thus, the energy level of the product is always higher than that of the reactants. During endothermic phase change, the potential energy of the system always increases while the kinetic energy of the system remains constant. The potential energy of the reaction increases because energy is been added to the system from the external environment.
