A Low pH, low PCO2, and low bicarbonate level
B High pH, low PCO2, and high bicarbonate level
C Low pH, high PCO2, and high bicarbonate level
D High pH, low PCO2, and low bicarbonate level ✓

Explanation

Respiratory alkalosis is characterized by a high pH (alkalosis), low PCO2 (hypocapnia), and a low bicarbonate level. This occurs when there is excessive ventilation, leading to a loss of CO2 from the body.
