<em>B. Middle Passage.</em>
Explanation:
Captive slaves were taken from the coast of Africa and to the Americas on the Middle Passage.
The Middle Passage was one of the stages of triangular trade. The first stage would involve the passage of goods like guns, cloth, and tobacco. The second stage was called the Middle Passage, which involved the passage of slaves from Africa to the Americas. Lastly, the third and final stage was the passage of the goods the slaves would produce to Europe, like cotton and indigo.
During the Middle Passage, many of the slaves on the ships would end up dying. They were in very cramped places, with little food and water. Since they were so cramped together and could not bathe, many would catch diseases from the uncleanliness. Not only this, but they would be beaten harshly, sometimes even thrown overboard.
