The Africans mainly provided raw materials in the trade between East Africa and Asia. the correct option among all the options given in the question is option "b". The East African cities and states were very eager to buy silk, cotton and porcelain objects that came from Asia. On the other hand they provided gold to the Asian traders as they were used for making coins and ornaments. The raw gold was found in good quantities in Africa during that time.

The correct answer is clearly B (what East Africa provides to Asia the most are raw materials). It is easy to comprehend, since raw materials are defined, by economists, as unprocessed goods, basic and natural material which is totally necessary to carry out properly the corresponding manufactures. In this case, mostly China turns to eastern Africa’s countries (Ethiopia and Zimbabwe, among others) so as to pull off the raw materials purchase.
