An experiment is carried out on a fixed amount of gas at different temperatures and at high pressure such that it deviates from the ideal gas behaviour. The variation of PVRT with P is shown in the diagram. The correct variation will correspond to: (Assuming that the gas in consideration is nitrogen)
