Correct answer: D — The most superior and anterior position in the glenoid fossae, against the posterior slopes of the articular eminences, with the articular discs properly interposed

Centric relation (CR) is defined as the maxillomandibular relationship in which the condyles articulate in the most superior-anterior position against the posterior slopes of the articular eminences, with the articular discs properly interposed. This is a bone-to-bone, musculoskeletally stable, reproducible position independent of tooth contact. It is the reference position for occlusal analysis, prosthodontic treatment planning, and TMD management. CR differs from maximum intercuspation (MI/CO) by typically 1-2 mm in most individuals.
