The correct answer is B. The name associated with assimilation policies is "Five Civilized Tribes".
Explanation:
The Five Civilized Tribes is the term for five Native American nations considered "civilized" by white society for having adopted many Western customs (including the possession of brick houses, plantations and black slaves and the use of European-style clothing) and to have good relations with their neighbors. These five nations were Cherokees, Chickasaw, Choctaw, Creeks and Seminoles.
The Five Civilized Tribes lived in the southeastern United States before being deported to other places, particularly to the future Ok Oklahoma
