B. Minute ventilation is the number of breaths taken each minute. Alveolar ventilation is the amount of air in the alveoli each minute. Minute ventilation is volume, not rate.
C. Minute ventilation is the volume of air moved into the upper respiratory tract each minute. Alveolar ventilation is the volume of air moved into the lower respiratory tract each minute. Both definitions are wrong.
D. Minute ventilation is the volume of air moved into the respiratory passages each minute. Alveolar ventilation is the volume of air that reaches the alveoli each minute. Minute ventilation = tidal volume × respiratory rate; alveolar ventilation accounts for dead space.
