For the chemical reaction the amount of AB at equilibrium is affected by

Generally amount of AB is affected byA) temperature    B) Pressure      C) ConcentrationΔn = 0, for the reaction pressure (or) volume has no effect on equilibrium state.A catalyst has no effect on equilibrium state assuming that the given reaction is extothermic (or) endothermic the amount of AB i.e. forward reaction is affected by temperature.Thus option (2) is correct
