A) Ghana's land was abundant and its location made it primed for successful trans-Saharan trade.
Step-by-step explanation:
The Empire of Ghana was located in the Sahel region, north of the abundant and generous gold fields of West Africa. It is known that its wealth came from administrative control of the gold mines, the exploitation of the salt deposits, the obtaining of the ivory, and, most importantly, controlling the trans-Saharan trade of these three products mainly.
The control of the commercial routes and the intense trans-Saharan commercial activity allowed it to extend borders by establishing and expanding various urban nuclei in its ever-expanding territory.
