What was the movement that sought to end racial discrimination in the U.S.?

The Civil Rights Movement was a pivotal period in American history, primarily during the 1950s and 1960s, focused on ending racial discrimination and ensuring equal rights for African Americans and other marginalized groups. This movement encompassed a range of campaigns and demonstrations aimed at abolishing segregation in public places, ensuring voting rights, and promoting equal employment opportunities.

Activists and organizations within this movement, such as the NAACP (National Association for the Advancement of Colored People), Martin Luther King Jr.’s Southern Christian Leadership Conference (SCLC), and the Student Nonviolent Coordinating Committee (SNCC), employed various strategies, including peaceful protests, legal challenges, and grassroots organizing. Key events, such as the March on Washington and the Selma to Montgomery marches, became symbols of the struggle for civil rights.

In contrast to the other movements listed, which focused on women's rights, labor rights, or environmental issues, the Civil Rights Movement specifically targeted racial injustice and worked towards achieving social equality, making it the correct answer to the question.
