Altitude Sickness Occurs When a Hiker Ascends to Altitudes Where

Altitude sickness occurs when a hiker ascends to altitudes where the density of oxygen is low. Carbonic anhydrase inhibitors cause less movement of carbonic acid toward carbon dioxide production and are used as a prophylactic treatment of altitude sickness. How does this treatment decrease the symptoms of high altitude sickness?

A) The resulting rise in pH increases respiration rate.
B) Excess bicarbonate ions are excreted in the urine and the resulting loss of blood pressure increases respiration rate.
C) An increase in blood acidity leads to an increase in ventilation.
D) An increase in bicarbonate ions in the blood stimulates the production of more red blood cells.
E) The excess bicarbonate ions in the blood increase the affinity of hemoglobin for oxygen.
