The correct answer is A) seizing control of government property to gain national attention.
The tactic that American Indian Activists used in the 1960s and 1970s that differed from tactics used by African American and Hispanic American activists was seizing control of government property to gain national attention.
The American Indian Movement was founded in 1968 in Minneapolis by George Mitchel, Deniss Banks, and other people to fight for the rights of the Native American Indians. The activist group wanted the Indians traditions to be respected, they wanted better economic conditions for Indian people living in city ghettos, protection of legal rights, and the restoration of their original lands.
