Which movement aimed to eliminate racial discrimination in the United States?

The Civil Rights Movement is indeed the correct choice as it was specifically focused on eliminating racial discrimination and ensuring equal rights for all citizens, particularly African Americans. This movement emerged in the mid-20th century, gaining momentum during the 1950s and 1960s, as activists fought against segregation, disenfranchisement, and other forms of racial injustice. The movement was marked by significant events such as the Montgomery Bus Boycott, the March on Washington, and the passage of landmark legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

In contrast, the Labor Movement primarily sought to improve working conditions and labor rights, focusing on issues like fair wages and the right to unionize. The Women's Suffrage Movement aimed to secure voting rights for women and did not specifically address racial issues. The Environmental Movement centers around the preservation and protection of natural resources and the environment, which, while important, does not focus directly on racial discrimination. Each of these movements plays a crucial role in U.S. history, but the Civil Rights Movement is distinctly centered on the fight against racial discrimination.
