Final answer:
African contributions to the American food inventory notably include A.okra, B.yams, and certain types of rice production, while C. corn and D. pumpkin are native to the Americas and not introduced by Africans.
Step-by-step explanation:
The food products contributed to the Americas from its African population include A.okra, B.yams, certain types of rice production, and other crops like groundnuts and sesame seeds.
However, it is important to note that C.corn and D. pumpkin were indigenous to the Americas and were not introduced by African populations.
Instead, they were Native American crops that became staples in different societies after the Columbian Exchange.
African crops like yams and the African variety of rice, along with other vegetables, became part of the diet in the Americas through the influence of the African population, particularly in the context of slavery where enslaved Africans used their agricultural knowledge to cultivate these crops.
