Which of the Following Statements Is NOT Correct

Which of the following statements is NOT correct?

A) An increase in temperature causes an increase in pressure of a gas because the frequency of molecules colliding with the walls of the container increases.
B) An increase in temperature causes an increase in pressure of a gas because the average force exerted by molecules colliding with the walls of the container increases.
C) All gases behave like ideal gases at sufficiently low pressures and high temperatures.
D) The ratio PV/nRT for a real gas can be less than 1 because of attractive forces between molecules.
E) The pressure exerted by oxygen molecules is greater than the pressure exerted by nitrogen molecules in a balloon filled with air because oxygen molecules are heavier.
