Correct answer: C — Centric stops (holding contacts)

Centric stops (holding contacts, supporting cusps in opposing fossae or marginal ridges) are the functional occlusal contacts that maintain the vertical dimension of occlusion and bear occlusal forces during maximum intercuspation. The supporting (centric holding) cusps are the palatal cusps of maxillary teeth and buccal cusps of mandibular teeth. Loss of centric stops (from wear, extraction, or restoration failure) leads to loss of vertical dimension.
