The correct option is: The particles will have the same average kinetic energy and the same temperature during boiling.
During the boiling process, the temperature of the liquid remains constant even though heat is being added, as the energy is used to convert the liquid into gas (vapor). The particles have an average kinetic energy that corresponds to the boiling temperature, and while individual particles may have different kinetic energies, they maintain the same average kinetic energy throughout the boiling process.
