Which is an example of the kinetic-molecular theory not holding true for a gas?

The kinetic-molecular theory assumes gas particles have negligible attractions and move freely between collisions. The theory does not account for attractions that can make a gas condense at low temperatures, so C describes a situation where its assumptions fail. Straight-line random motion, temperature-dependent average kinetic energy, and particles occupying little of the gas’s total volume are all assumptions of the theory.
