The autoionization of water is endothermic, which means it requires an input of energy to occur. As the temperature of water is raised, the autoionization becomes more favorable since there is more thermal energy available to break the hydrogen bonds between water molecules. However, it's important to note that raising the temperature of water does not affect the equilibrium constant of the autoionization reaction, which is a constant at a given temperature. As a result, the pH of the water does not change significantly, and remains neutral. Therefore, option C is correct.
