Sinusitis is best described as inflammation of which structure?

Explanation:
Sinusitis specifically means inflammation of the sinuses—the air-filled spaces in the skull that connect to the nasal passages. The word ends with -itis, indicating inflammation, and the root sinuses identifies the affected structures. When these passages become inflamed, the mucosa swells and drainage is blocked, leading to pressure, congestion, facial pain, and nasal discharge. The other options point to inflammation of different organs (lungs, kidneys, arteries), not the sinuses, so they aren’t the description of sinusitis.
