Answer:
D) the Mississippians
Step-by-step explanation:
The Mississippian culture was a Chalcolithic culture of North America that flourished in the Midwest, East and Southeast of the present United States approximately between 800 and 1550.
The Mississipian lifestyle was born in the valley of the Mississippi River (from which it takes its name). The cultures of the Tenesi river valley could also begin to develop Mississippian characteristics at this time. Almost all the Mississippian sites predate 1539 (when Hernando de Soto explored the area), and very few artifacts of this culture have been discovered, which indicates that it disappeared almost completely before coming into contact with Europeans.
