The correct answer to this question could be A + B ↔ AB. When dealing with pressure, you need to count the number of moles on both sides of the equation. If there is an increase in pressure, the reaction favors the direction with a lower number of moles.

If there is a decrease in pressure, the reaction will favor the direction with more moles of molecules. Because there are 2 moles of substance on the left and 1 on the right, if the pressure is increased, the reaction will favor the side with a fewer moles of molecules, which in this case is the forward reaction.
