(A) In the reaction $A_{2(g)} + B_{2(g)} \rightleftharpoons 2AB_{(g)}$,the number of moles of gaseous reactants is $1 + 1 = 2$ and the number of moles of gaseous products is $2$.Since the total number of moles of gas on both sides of the equation is equal $(\Delta n_g = 2 - 2 = 0)$,the equilibrium position is unaffected by changes in pressure.
