C Correct answer
Explanation

The nasopulmonary and nasothoracic reflexes govern the mechanism of breathing through deepening the inhale. Triggered by the flow of air, the pressure of the air in the nose, and the quality of the air, impulses from the nasal mucosa are transmitted by the trigeminal nerve to the breathing centres in the brainstem and the generated response is transmitted to the bronchi, the intercostal muscles and the diaphragm.
