Which one of the following is not a fundamental assumption about the structure of gases in the kinetic theory of gases model ?

1. (a) A gas is composed of a very large number of minute particles (atoms/molecules)
2. (b) In the absence of a force field, these particles move in a straight line
3. (c) These particles interact (collide) with one another only infrequently
4. (d) In any collision, the total kinetic energy of the two molecules may change after the collision
