NEET Physics Question - Thermal Physics

Which of the following is not the correct assumption of kinetic theory of gases?

No intermolecular force acts between gas molecules.

The volume of molecules is negligible in comparison to the volume of gas.

Molecules only collide with the walls of container, there is no collision among the molecules.

All collisions are elastic.

Kinetic theory assumes that gas molecules undergo continuous random motion and collide with each other as well as with the walls of the container.
