Which of the following movements is associated with fighting against racial discrimination?

The Civil Rights Movement is specifically associated with fighting against racial discrimination, particularly in the United States. This movement, which gained significant momentum during the 1950s and 1960s, focused on ending segregation and securing equal rights for African Americans and other marginalized communities. Key events, such as the March on Washington and the enactment of landmark legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965, were central to achieving these goals.

In contrast, while the Labor Movement fought for workers' rights and better labor conditions, and the Suffrage Movement focused on securing voting rights for women, these movements, although they intersect with issues of equality, do not primarily address racial discrimination. The Environmental Movement, on the other hand, is concerned with the protection of the environment and does not directly relate to racial issues. Therefore, the Civil Rights Movement is the clear choice in this context as it specifically targets the fight against racial discrimination.
