The interaction between Europeans and Africans in the fifteenth and sixteenth centuries is appropriately described by Option A.
European nations conducted trade with several African kingdoms during this time. Along with the horrible practice of chattel slavery, the trade involved the exchange of goods, including important commodities like gold and other resources.
Trade agreements involving the exchange of enslaved people as commodities were frequently negotiated by European traders with African chiefs. The transatlantic slave trade began with this, and it had a significant and long-lasting impact on both continents.
