Answer:
C) To get the white man to sympathize with their living conditions on reservations and make them reevaluate what was done to them years before.
Explanation:
A group that called themselves "Indians of All Tribes" occupied Alcatraz Island between 1969 and 1971 to make a stand and protest about the living conditions and the American policies which took their lands away from them and this was done to bring focus and sympathy and in the end, the government made some changes in the law which helped them preserve their culture and respect their land rights.
