Final answer:
Body structure is not commonly used to determine race. Historically, skin color, hair texture, and eye shape and color are the traditional criteria, though these are not scientifically valid indicators of race.
Step-by-step explanation:
The question asks about the physical characteristics used to determine race.
All of the options listed - skin color, hair texture, and eye color - have historically been used to circumscribe racial categories, albeit incorrectly so, as races do not have distinct biological foundations. However, body structure is not a characteristic commonly used to determine race.
In the U.S., three main criteria have been used traditionally: skin pigmentation, hair texture and color, and eye shape and color, tends to generate the categories of White, Black, and Asian. Nevertheless, anthropologists and geneticists affirm that race as a concept is not valid scientifically, and the three-factor test often excludes millions from Latin America, requiring additional categories to be created.
