All of the following were item the Aksum traded except

A. Ivory

B. Gold

C. Cotton

D. Gold

Ivory and gold are both items the Aksum sold; I am not sure if the correct answer is cotton or salt. Cotton is believed to have originated in the Indus Valley, and I know salt was a major trade item in Ghana. If you know that Ghana and the Askum people traded with each other, then you know they were not involved in trading cotton.

The answer is Cotton, good luck
