A scientist explains that ocean acidification can reduce the saturation state of calcium carbonate minerals. This occurs because CO2_2 absorption increases carbonic acid and H+^+, which reduces CO32−_3^{2-}. Which outcome is most likely when saturation state decreases? A. CaCO3_3 structures are more likely to dissolve or form more slowly B. CaCO3_3 structures form faster because more carbonate is available C. Seawater pH increases because H+^+ is removed D. Acid rain becomes the primary driver of open-ocean pH trends
