A、American. B、European. C、Indian. D、Tribal. CWhose languages have given many words to English?

The word "okay" is known and used by millions of people all over the world. Still, language experts do not agree on where it came from. Some say it came from Indian people. When Europeans first came to America, they heard hundreds of different Indian languages. Many were well developed. One tribe especially had a well developed language. They were farmers and fishermen who lived in the rich Mississippi valley in what is now the state of Alabama. When problems arose, the headers of this tribe discussed them with the tribal chief. They sat in a circle and listened to the wisdom of the chief. He heard the different proposals often raising and lowering his head in agreement, and saying, "okeh," meaning, "all is so". The Indian languages have given many words to English. Many American states have Indian names, and so do rivers, streams, mountains, cities and towns.
