Correct answer: D — Torus mandibularis

Torus mandibularis is a common benign exostosis (bony outgrowth) located on the lingual aspect of the mandibular body, typically bilateral and in the premolar region. It is covered by thin, intact mucosa and is firm, non-tender, and non-fluctuant on palpation. Prevalence varies by ethnicity (up to 40% in some populations). No treatment is needed unless it interferes with denture fabrication, oral function, or biopsy is needed for diagnostic purposes. It is composed of dense lamellar bone.
