C. Was the only kind of labor on that continent

Explanation:

Slave has long existed within the African society. Slavery in which most of the slaves are used as forced labor existed in many African kingdoms and societies for hundreds of years.

Slave practices in Africa comes from the major African Kingdoms, especially along the coast, and evidence of widespread slavery practises used as a form of labor can be seen in stateless societies.

D. Involved the enslavement of criminals, debtors, and war captives.

Explanation:

Slavery in Africa existed before the arrival of the Europeans. Prior to colonial times, Africans already dealt with the business of slavery, particularly in certain regions. Slavery was considered an appropriate punishment for certain criminals, debtors and war captives. When the European colonizers began to get involved in the business of slavery, they were able to join these networks that were already developed in Africa, expanding the business to a global enterprise.
