Dr. Vane deploys a microscopic survey probe into the sealed test chamber of the Stratosphere Cruiser, where a mixture of light neon vapor and heavy krypton gas has reached thermal equilibrium at 350 K. The probe's sensors log thousands of particle collisions per second against the chamber walls and between individual atoms. According to the kinetic molecular theory of gases, which statement accurately compares the behavior of the two gases inside the chamber?

A) The krypton atoms possess a significantly greater average kinetic energy than the neon atoms because of their larger atomic mass.

B) The neon atoms experience frequent inelastic collisions, permanently losing total kinetic energy upon striking the krypton atoms.

C) Both gases share the exact same average kinetic energy, but the neon atoms move with a higher root-mean-square speed than the krypton atoms.

D) The krypton atoms exert stronger mutual attractive forces on each other, causing their paths between collisions to curve noticeably.
