Correct answer: B — Centric relation (CR) record

After the maxillary cast is mounted using the facebow record, the mandibular cast is mounted using a centric relation (CR) record. This is a jaw relationship record taken with the mandibular condyles in their musculoskeletally stable position (CR). The record material (wax wafer, polyvinyl siloxane bite registration, Lucia jig with zinc oxide paste) captures the relationship and allows accurate articulation. Protrusive and lateral records are used to set the condylar guidance angles.
