Which of the following was the chief means of transport during the Tran-Saharan Trade?

During the Tran-Saharan Trade, the chief means of transport was camels. Camels were well-suited to the harsh desert environment and could carry heavy loads over long distances without requiring much water. They were able to traverse the vast Sahara Desert and were commonly used by traders to transport goods such as gold, ivory, and salt from West Africa to North Africa and the Mediterranean. Camels also provided a means of transportation for people, and were used by merchants, nomads, and armies to cross the desert.
