Which One of the Following Statements Regarding Partial Pressures and Kinetic

Which one of the following statements regarding partial pressures and kinetic molecular theory is NOT correct?

A) The total pressure of a gas mixture will reflect the force with which the gas molecules collide with the container walls,independent of molecular identities.
B) The total pressure of a gas mixture will reflect the frequency with which the gas molecules collide with the container walls,independent of molecular identities.
C) The total pressure of a gas mixture will reflect the average kinetic energy of the gas molecules,independent of molecular identities.
D) Molecules of each gas in a mixture contribute to the total pressure in exact proportion to their relative number in the container.
E) Heavier gases contribute more to the total pressure in a gas mixture because their average kinetic energies are higher.
