The correct answer is C. The two groups that led armed protests during the 1960s were the Black Panthers and the American Indian Movement.
The Black Panthers, in its beginnings in October 1966, had as their main activity the formation of patrols of armed citizens to monitor the behavior of police officers, and thus challenge the police brutality against African-Americans in Oakland, California. In 1969, it established social programs aimed at the community, which became the main activity of the party. The most famous were free breakfasts for children and local health clinics.
The American Indigenous Movement was an American civil rights organization founded in 1968, originally created to assist indigenous displaced persons in cities through government programs.
With the contemporary explosion of the Black Panthers, and the organizations inspired by it, they used the structure and mode of action of the former, combining them with traditional elements of the aboriginal struggle.
