Effect of inert gas addition -

If the volume is kept constant and an inert gas such as argon is added which does not take part in the reaction, the equilibrium remains undisturbed. It is because the addition of inert gas at constant volume does not change the partial pressures or the molar concentration. The reaction quotient changes only if the added gas is a reactant or product involved in the reaction.

Therefore, option number (4) is correct.
