Answer:
Option: A. Gold was discovered in the Black Hills on land belonging to the Sioux.
Explanation:
The outbreak between the US Army and American Indians began because of the presence of gold in the Black Hills. Historically, after conquering the Cheyenne in 1776, the Lakota (tribe) took the area of the Black Hills, which emerged as a center of their culture. The conflict began to control the region over the Black Hills, which came to be known as the Great Sioux War. The result of the war was dreadful for Lakota, Cheyenne and Arapaho.
