The correct answer would be
A. The Triangular Trade. Otherwise known as the transatlantic slave trade, from
16th to early 19th centuries, slaves were being traded
along with cash, crafts, and other goods. The involved areas in the world were
Africa, American Colonies, and European colonies. The slaves were required to
grow crops needed for export to other countries and these countries brought
some of the people for slavery as well. The Middle Passage was the route to
which the slaves were brought from Africa to America.
