Answer:
Towards the products, or to the right
Step-by-step explanation:
There are no provided answer choices, but the answer should be to the right.
By Le Chatelier's principle, which basically can be summarized as "if you mess with chemistry, chemistry messes back", if more reactants are added, the equilibrium will shift to the right towards the products in order to make more products and counteract the increase in I₂.
