The correct answer is - Slaves.
The West African empires had a tradition of having lot of slaves, usually people that were captives in war. The smaller tribes in West Africa that were ruled by the bigger tribes or empires, were very often treated very badly, and lot of their people were taken as slaves.
When the Europeans saw the potential of the slaves, they rushed to negotiate and buy them off, and for the West African empires it seemed like an easy way to make big profits, so the trade with slaves started. Millions of people were used in the so called Atlantic Slave Trade, most of whom are the descendants of the black populations in the Americas.
