Correct answer: (c) At high pressure and low temperature
Explanation:
At high pressure and low temperature, gaseous atoms or molecules get closer to each other and van der Waal forces operates.
So molecules or atoms start attracting each other. Hence a gas deviate the most from its ideal behaviour. While in ideal behaviour we consider that gaseous molecules do not attract each other, i.e., there is no intermolecular forces of attraction.
