Clarification IMAT 2016 Q45

Suite du sujet IMAT 2016 Q45 [Equilibrium] :

Hello in this question I just wanted to be sure :
3 is correct because adding sodium hydroxide to the mixture will make the solution more basic so the reaction will shift into making an acid hence shift to the left ?

that is a correct explanation but here is how I would solve it:
as NaOH ionizes, there will be extra OH molecules in the solution and the extra stress can be decreased by using the OH molecules, hence going to the left side making them compounds
hope it helps!
