A. White settlers began wanting the land on the Plains

Explanation:

Initially, the Great Plains were given to the Native Americans as place where they can live freely and as they did prior to the white settlers, thus they were one very large reservation. This changed though as the time passed by, and the great potential of the Great Plains was noticed by the white settlers, thus they started wanting the land. The Great Plains were vast, they had soil of excellent quality, and weather conditions that were suitable for large scale farming. This led to conflict between the white settlers and the Native Americans, with the white settlers coming out as winners, and gradually taking over the ''fruit basket'' of North America into their possession, gradually turning it into one of the most productive agricultural regions in the world.
