For 1-mol sample of gas in a 1-L container, the graph for the change in pressure as the temperature increases is shown below. The four plots represent an ideal gas and three real gases: sulfur dioxide (SO₂), argon (Ar), and ammonia (NH₃).

Given the van der Waals constants below, assign the gases (SO₂, Ar, NH₃) to their corresponding plots (A, B, C).
