Correct answer: E — Upper second molar

The correct answer is E, the upper second molar. The parotid duct, also called Stensen's duct, opens through the parotid papilla on the buccal mucosa opposite the maxillary second molar. This is the standard intraoral landmark used when examining the duct or attempting duct cannulation. The upper first molar and second premolar are too anterior, while the upper third molar is too posterior. The lower second molar is in the wrong dental arch because the parotid duct opens into the maxillary buccal vestibule.
