Answer

The correct answer is Graph C. The average kinetic energy of the molecules of a gas increases linearly with temperature. This relationship reflects that as temperature increases, the kinetic energy of gas molecules also increases proportionally. Thus, the graph that depicts a straight line upwards is the accurate representation.
