Correct answer: C — The mesiobuccal cusp of the mandibular first molar is mesial to the mesiobuccal groove of the maxillary first molar

In Angle Class III malocclusion, the mandibular first molar is positioned mesially (anteriorly) relative to the maxillary first molar — the mesiobuccal cusp of the mandibular first molar occludes mesial to the mesiobuccal groove of the maxillary first molar. This often presents with an anterior crossbite (negative overjet) and may involve mandibular prognathism, maxillary deficiency, or both.
