The Ghana Empire (300s-1200s CE) would have been most likely to have traded with Muslim caravans. (Option "A" is the correct answer)
The Ghana kingdom developed as a West African empire since its wealth was due to the trans-Saharan trade with salt and gold. The Berber-speaking people who became Muslims with the Muslim conquest of the Maghreb, crossed the Sahara Desert so as to commerce with the Ghanaians. Thanks to the introduction of the camel which allowed a trade network from Morocco to the Niger River, the Muslims from North Africa were able to increase commercial transactions with the Ghanaians. As a result, the Ghana Empire became more powerful and rich . Not only did the Ghana rulers encourage the development of urban centres, but also the expansion and control of trade routes.
