Please help I will mark BRANLIEST!!thanks What conclusion may be drawn from the dramatic increase in slave importation that took place from the early 1700s until the mid-1800s?

A) Imported Africans were kept in such isolation that no cultural exchange of goods or traditions occurred between imported Africans and inhabitants of the Americas.

B) Imported Africans were used almost solely as Laborers, but vast cultural exchanges of goods and traditions occurred between imported Africans and inhabitants of the Americas.

C) Imported Africans were used to such a great degree that the cultural goods and traditions of the imported Africans completely destroyed the cultural goods and traditions of the Americas.

D) Imported Africans were used almost always allowed to go free once in the Americas, so and cultural exchanges of goods and traditions that occurred between imported Africans and inhabitants of the Americas were short-lived, since most imported Africans returned to their homeland.
