4. Consider three identical flasks filled with different gases: Flask A, CO at 760 torr and 0°C； Flask B, N₂ at 250 torr and 0°C； Flask C, H₂ at 100 torr and 0°C. Which one of the following statements is consistent with the conditions described above?
(A) Ranking the gases in order of increasing average kinetic energy: Flask A＞ Flask B ＞ Flask C
(B) Ranking the gases in order of increasing average velocity: Flask A ＞ Flask B ＞ Flask C
(C) Ranking the gases in order of increasing average velocity: Flask B ＞ Flask A ＞ Flask C
(D) Ranking the gases in order of increasing average kinetic energy: Flask A = Flask B = Flask C
(E) Ranking the gases in order of increasing average kinetic : Flask A ＜ Flask B ＜ Flask C
