[2025-10-01T08:20:20.075314] [PI reasoning] **Evaluating dental traits**

I'm trying to analyze a question about ethnic dental traits. For statement A, it seems true that Mongoloid populations often lack upper third molars, which could suggest that it’s common among them. Statement B appears true too, since the Carabelli cusp is found more often in Caucasoid populations. However, statement C is incorrect because shovel-shaped incisors are a characteristic of Mongoloid populations, not Africans. So, I conclude statement C is false regarding ethnic dental features.
