The answer is the option A.) This is a limitation of the kinetic-molecular theory. Indeed gases at high pressures and low temperatures apart from ideal gas behavior and do not meet the kinetic-energy postulates. The main postulate of the kinetic-energy theory is that molecules are separated by empty space and there is not intermolecular forces acting.
