Answer:Southern Christian Leadership Conference (SCLC)
Congress of Racial Equality (CORE)
Student Nonviolent Coordinating Committee (SNCC).
Explanation: I got the answer right on USATestPrep. The SCLC was founded in 1957 by MLK and worked with local organizations. CORE was founded by a group of college students in 1942, and helped to organize peaceful movements like the Montgomery Bus Boycott. The NAACP is the oldest civil rights movement in the United States. The SNCC helped plan sit-ins, voter registration drives, and protests.
