Correct answer: B — Retromolar pad
The retromolar pad serves as the posterior landmark for both the buccal and lingual flanges of the mandibular complete denture. The lingual flange extends from the lingual frenum (anteriorly) to the retromolar pad (posteriorly), with its depth determined by the mylohyoid muscle action and sublingual gland position. The lingual flange must be properly contoured to accommodate the mylohyoid muscle (S-shaped in cross-section) and the sublingual gland.
