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

The Civil Rights Movement is the correct choice as it specifically focused on addressing and eliminating racial discrimination and segregation in the United States. This movement, which gained significant traction in the 1950s and 1960s, sought to challenge the systemic injustices that African Americans and other minorities faced, particularly in areas such as voting rights, public accommodations, and education.

Through various forms of protest, including peaceful demonstrations, court cases, and legislative advocacy, leaders like Martin Luther King Jr., Rosa Parks, and Malcolm X contributed to a broader push for equality, which ultimately led to landmark legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965. These efforts were aimed specifically at dismantling the institutionalized racism prevalent in society.

In contrast, while the Suffrage Movement focused on securing women's voting rights, the Labor Movement aimed to improve working conditions and workers' rights, and the Environmental Movement seeks to address ecological issues, none of these movements directly targeted racial discrimination as the primary goal, making the Civil Rights Movement the most relevant option.
