What movement aimed at ending racial discrimination?

The Civil Rights Movement is the correct choice because it specifically focused on ending racial discrimination and securing equal rights for African Americans and all individuals facing racial injustice. This movement emerged prominently in the mid-20th century, especially during the 1950s and 1960s, addressing systemic racism and advocating for legal reforms and societal change. Key events such as the Montgomery Bus Boycott, the March on Washington, and the passage of landmark legislation, such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965, were pivotal in advancing the goals of the movement.

In contrast, the Suffrage Movement primarily sought to secure voting rights for women. The Labor Movement focused on improving conditions and rights for workers. The Environmental Movement is centered around protecting the environment and addressing issues related to conservation and sustainability. Each of these movements has its significance, but they do not specifically target racial discrimination in the manner that the Civil Rights Movement did.
