Explanation
Choice A rationale:

Choice B rationale:
The nasopharynx does not primarily filter dust. This function is mainly performed by the nasal cavity and the hairs within the nostrils.
Choice C rationale:
The nasopharynx provides openings for the right and left Eustachian tubes. These tubes connect the middle ear to the nasopharynx and help equalize air pressure on either side of the eardrum.
Choice D rationale:
The nasopharynx does not contain olfactory receptors responsible for the sense of smell. These receptors are located in the nasal cavity.
