Step-by-step explanation:
Chief Joseph, Geronimo, and Sitting Bull have several things in common, but the most prominent would be that B) They were all Native American leaders. These leaders were renowned for their resistance to the policies enforced by the American government related to Native American lands and sovereignty. They were not born in the same year and not all of them were strictly military commanders. Also, none of them supported the American government's policies; instead, they are known for their opposition and resistance to them.
For instance, Sitting Bull, a Lakota Sioux spiritual leader, was known for uniting tribes to resist forced removal and for his significant role in the defeat of George Armstrong Custer at the Battle of Little Bighorn. Ultimately, all these leaders were involved in struggles to protect their people's way of life and land against the encroachment of the United States.
