[2025-10-02T08:37:35.183718] [PI reasoning] **Determining alloy composition**

I have a question on cobalt-chromium alloys, particularly their composition. In dentistry, Co-Cr alloys are often used for removable partial dentures, with typical compositions being 60% cobalt, 30% chromium, 5% molybdenum, and a bit of carbon. So, option B looks correct. I might also note standard references like Boucher's Prosthodontics or Phillips' Dental Materials. I'm recalling literature like Craig's Restorative Dental Materials, but I could check PubMed for further confirmation on the alloy's composition.
