Correct Answer is D
Explanation
A. Hypoventilation due to acidosis: Hypoventilation would increase CO₂, leading to respiratory acidosis, not hypocapnia.
B. Hypoventilation due to alkalosis: Hypocapnia is a result of hyperventilation, not hypoventilation.
C. Hyperventilation due to acidosis: Hyperventilation is a response to acidosis to blow off CO₂, but hypocapnia itself is a result of hyperventilation.
D. Hyperventilation due to alkalosis: Hypocapnia (low CO₂) leads to respiratory alkalosis. This occurs due to hyperventilation, which blows off too much CO₂.
E. Hypocapnia does not affect ventilation rate: CO₂ levels significantly influence ventilation via central chemoreceptors.
