Explanation:
Adsorption:
Adsorption is a process where a gas or liquid accumulates on the surface of a solid or a liquid. There are two types of adsorption: physisorption and chemisorption. In physisorption, the adsorbate (gas or liquid) is held by weak van der Waals forces, while in chemisorption, the adsorbate is held by chemical bonds.
Factors affecting adsorption:
The extent of adsorption depends on several factors, including the nature of the adsorbate and the adsorbent, temperature, pressure, and surface area of the adsorbent.
Critical temperature and pressure:
The critical temperature and pressure of a gas are the highest temperature and pressure at which the gas can exist in a liquid state. These values are important in determining the behavior of gases at high temperatures and pressures.
Effect of critical temperature on adsorption:
The extent of adsorption is influenced by the critical temperature of the gas. Gases with higher critical temperatures are more likely to be adsorbed on a solid surface because they have a greater tendency to condense into a liquid or solid state. This is because, at a higher temperature, the kinetic energy of the gas molecules is higher, and they are less likely to be attracted to the surface of the adsorbent. On the other hand, gases with lower critical temperatures are less likely to be adsorbed because they have a lower tendency to condense into a liquid or solid state.
Conclusion:
Therefore, the correct answer is B, as gases with higher critical temperatures are more likely to be adsorbed on a solid surface, as they have a greater tendency to condense into a liquid or solid state.

B is correct becoz higher the critical temperature of the gas. Greater is the ease of liquefaction. i.e. greater Vander walls forces of attraction and hence large adsorption will occur.
