Quizplus · Accepted Answer

According to the Bohr effect, when pH drops (blood becomes more acidic), the affinity of Hb for oxygen decreases (option I) and the Hb saturation for a given PO₂ falls (option II). Option III is incorrect as the Hb saturation decreases with the drop in pH. Therefore, the correct answer is A (I and II).
