C) a low respiratory rate and high tidal volume
D) a low respiratory rate and very low tidal volume

Alveolar ventilation rate is the amount of air per minute that reaches the alveoli for gas exchange. It is calculated by subtracting the dead space (air that fills the conducting zone and does not participate in gas exchange) from the tidal volume, and then multiplying the result by the respiratory rate. A low respiratory rate and very low tidal volume (option D) would result in a lower alveolar ventilation rate because there is less air reaching the alveoli for gas exchange.
