detailed solution

Correct option is A

As the molecular weigth ↑es,Surface area ↑es,and hence vander waal's force of attractions ↑es• The adsorption phenomina (physical) depends upon the vander waal's force of attraction and surface area .• Therefore D2 is more rapidly adsored on surface than H2, As surface area of D2 grater than that of H2, & hence vander waal's force of attractions are more in D2 than in H2 with catalyst Statement I and Statement II are true.
