Solution

The correct option is C Bronchi
When a person takes in a breath of air, the air travels through the nose or mouth, into the larynx, then into the trachea, which is the main passageway into the lungs. The trachea divides into a right and left main bronchus (singular of bronchi). Each major bronchus then subdivides into smaller airway passages referred to as bronchi.
