Why would the earliest people from the Oklahoma area have not remained there

The correct answer is B) lack of food.

The earliest people from the Oklahoma area have not remained there due to a lack of food.

Historians and archeologists think that the first humans in the Oklahoman territory were the Clovis people. Prehistoric Native people could have inhabited the territory of Oklahoma, 20 to 17,000 years ago. Then, it comes the time of early people that developed better hunting techniques, the Clovis and the Folsom cultures, that inhabited these territories 12,000 to 15,000 thousand years ago. They were hunter-gathered people that follow the herds to hunt them.
