Final answer:
A low pH in the tissues, indicated by increased acidity, will not facilitate the transfer of oxygen to tissues. This is because the decrease in pH reduces the affinity of hemoglobin for oxygen, making it more difficult for oxygen to be delivered to the tissues.
Step-by-step explanation:
The correct answer is c) Low pH in the tissues. A low pH in the tissues, which indicates increased acidity, will not facilitate the transfer of oxygen to tissues. When acidity increases, such as from increased carbon dioxide in the blood, the pH decreases. This decrease in pH reduces the affinity of hemoglobin for oxygen, causing the oxygen to dissociate from hemoglobin and making it more difficult for oxygen to be delivered to the tissues
