In an experiment demonstrating the evolution of oxygen in Hydrilla, sodium bicarbonate is added to water in the experiment set-up. What would happen if all other conditions are favorable?

Amount of oxygen evolved increases as the availability of carbon dioxide increases

Amount of oxygen evolved decreases as the availability of carbon dioxide increases

Amount of oxygen evolved decreases as carbon dioxide in water is absorbed by sodium                   bicarbonate
