Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Acute apical abscess
An acute apical abscess is a localized collection of pus around a tooth apex, usually after pulpal necrosis. Drainage and removal of the source are central to management.
Option by option

Dentin hypersensitivity causes short sharp stimulus-related pain without infection.
B. Reversible pulpitis
Reversible pulpitis does not produce facial swelling or pus.
C. Acute apical abscess (correct)
Correct. Percussion tenderness, swelling, and apical pus fit an acute apical abscess.
D. Pericoronitis
Pericoronitis is inflammation around an erupting, usually mandibular, third molar.
