Which meatus contains the nasolacrimal duct?

The nasolacrimal duct drains tears from the eyes into the nasal cavity. It opens into the inferior meatus of the nasal cavity, which makes option C the correct answer.

Options A, B, and D are incorrect:

• The superior meatus (Option A) drains the posterior ethmoidal sinus and the sphenoidal sinus.
• The middle meatus (Option B) contains the openings of the frontal sinus, maxillary sinus, and anterior ethmoidal cells.
• The posterior meatus (Option D) contains the opening of the nasopharynx.
