Answer: B

Reasoning: In a standard Ward’s/triangle flap for mandibibular third-molar removal, the distal limb is swept buccally so that the incision and subsequent flap elevation stay on the buccal (cheek) side of the alveolar ridge. This keeps surgical instruments and sutures away from the lingual gingiva where the lingual nerve courses just beneath the mucosa, thereby reducing the risk of nerve trauma [La Monaca 2017, PMID 29299188; Lata 2011, PMID 22639500].
