At the end of the 15th century, Spanish and Portuguese explorers who arrived in Africa were not looking for slaves: gold was their object of desire. However, this situation changed with the development of sugarcane and similar plantations in America because these required numerous workers, willing to undergo arduous working conditions, especially during harvest. Besides this, the labor force needed to be cheap to allow colonizers to take profit for plantations. This along with the fact that European free workers were not willing to work under these conditions, and that the native's population had almost disappeared due to diseases carried by the Europeans to America, made colonizers enslaved people in Africa as in this way, they did not have to give workers in plantations any payment and they were resistant to diseases and weather conditions. So, the correct answer is B. Africans.
