Identify the correct labels of A,B and C in the following graph from the options given below :


Root mean square speed (V_rms); most probable speed (V_mp); Average speed (V_av)

Points I, II and III in the following plot respectively correspond to
(V_mp : most probable velocity)

Consider the following table :

Gas	a/(k Pa dm6 mol-1)	b/(dm3 mol-1)
A	642.32	0.05196
B	155.21	0.04136
C	431.91	0.05196
D	155.21	0.4382

a and b are vander Waals constants. The correct statement about the gases is :

At a given temperature T, gases Ne, Ar, Xe and Kr are found to deviate from ideal gas behaviour. Their equation of state is given as

$$p = {{RT} \over {V - b}}$$ at T.

Here, b is the van der Waals constant. Which gas will exhibit steepest increase in the plot of Z (compression factor) vs p?
