The correct answer is B) It was the second part of a three- legged trade route where slaves were transported to the Americas.
On this "Middle Passage" slaves were crammed into crowded ships in order to be brought to America. The people who transported these slaves used a method known as "tight packing," essentially fitting as many slaves as possible onto a ship in order to maximize their profit upon arrival to the Americas. At many points, these slaves were unable to move and thousands would end up dying from sicknesses during this trip to the Americas.
