Option B - increase in pressure.
The extent of adsorption is directly proportional to the pressure. Therefore, increase in pressure will cause increase in rate of adsorption.

Keep in mind that temperature also has a role to play in the rate of adsorption. At low temperature, the extent of adsorption increases rapidly with pressure.
