Explanation:

Identify the organization

The question asks about the Congress of Racial Equality (CORE), a prominent Civil Rights Organizations group founded in Chicago in 1942.

Analyze the leadership options

Martin Luther King Jr. led the Southern Christian Leadership Conference (SCLC), not CORE. Rev. Ralph Abernathy was also a key leader of the SCLC, succeeding King. Thus, the first and fourth options are incorrect.

Evaluate the tactical options

CORE was founded in 1942 and pioneered the use of nonviolent direct action in America. In the 1940s, CORE famously organized some of the earliest sit-ins (such as the 1943 sit-in at Jack Spratt Coffee House in Chicago) to challenge racial segregation in public accommodations. This makes the third option historically accurate.

Answer:

• was led by Martin Luther King Jr.
• used boycotts in the 1960s to achieve integration.
• used sit-ins in the 1940s to encourage integration. (Correct answer)
• was led by Rev. Ralph Abernathy.
