Answer:
D. Decreased arterial PCO2
Explanation:
pO2 decreases exponentially with altitude, this leads to an increase in the respiratory rate in an attempt to gain equilibrium, this leads to a decreasing arterial pCO2, this will displace the equilibrium of gases exchanged resulting in a loss of H+ and leading to respiratory alkalosis, an increasing on arterial's pH.
