The correct answer is B) the Great Plains.
The Cheyenne, who lived in tipis while hunted Buffalo, lived in the region of the Great Plains.
The Cheyenne tribes used to live in different regions of the Great Plains before the United States moved them to a region in Oklahoma in the 1800s. The Great Plains includes the states of Colorado, Wyoming, Kansas, Nebraska, and South Dakota. Indeed, the capital city of the state of Wyoming is called, Cheyenne, as a tribute to those tribes.
