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 :
A
Gas C will occupy more volume than gas A; gas B will be more compressible than gas D
B
Gas C will occupy lesser volume than gas A; gas B will be more compressible than gas D
C
Gas C will occupy lesser volume than gas A; gas B will be lesser compressible than gas D
D
Gas C will occupy more volume than gas A; gas B will be lesser compressible than gas D
