Solution

(A) The gas A has lowest values of the vander waals constants a and b. Hence, it shows most ideal behavior around STP
(B) The gas B has highest value of the vander waals constant a . Hence, it has the highest critical temperature
(C) The gas B has highest value of the vander waals constant b. Hence, it has the largest molecular volume.
