B. We must be allowed to live independently of the white man's society.
Explanation:
Chief Joseph did not support federal assimilation efforts and believed that this was a strong disrespect for the native community as well as a clear attempt to suppress them and remove them from the land that was rightfully theirs. He claimed that the natives just wanted to maintain their survival, regardless of what the white man thought, they did not want to stop white men, but white men, tried at all costs to exterminate them.
Because of this, we can say that option B is the one that best represents Chief Joseph's argument.
