Answer:
The explorers were from:
D. Spain
Step-by-step explanation:
It was in 1540 that Spanish explorer Hernando de Soto first made contact with the Choctaws and the Chickasaws. Soto and his company of conquistadors were sent on an expedition, and he was the very first European to see the Mississippi river. He was buried in the river, as a matter of fact, after dying from a fever. Throughout his life as an explorer, Soto traveled to several places in the American continent, helping conquer lands. No wonder he did not receive any blessings from the natives upon his death.
