Rhinitis is an inflammation of which structure?

Explanation:
Rhinitis is an inflammation of the nasal mucosa, the lining inside the nasal cavity. This mucosa contains ciliated epithelial cells and goblet cells that humidify, warm, and filter air; when inflamed, it swells and produces excess mucus, leading to congestion, runny nose, and sneezing. The other listed structures—larynx, trachea, and bronchi—are parts of the airway lower or higher than the nasal cavity, and inflammation there would be laryngitis, tracheitis, or bronchitis, not rhinitis. So the nasal mucosa is the correct site.
