Answer:
The correct option here is B) differential in power.
Step-by-step explanation:
As per the Noel hypothesis Africans were chosen above other groups such as native Americans and other white groups because of differential in power . The whites had a more dominant position than the Africans, who were brought in to the country as cheap labor. According to this hypothesis if a couple of groups come together who were characterized by the features such as ethnocentrism, competition and differential in power , then this will lead to a racial stratification.
