Final answer:
The NAACP, since 1909, has been dedicated to achieving racial integration and played a pivotal role in historic events like the Brown v. Board of Education decision, which targeted the desegregation of public schools.
Step-by-step explanation:
The desegregation campaign was led largely by the NAACP, which had fought since its inception in 1909 to ensure the political, educational, social, and economic equality of minority group citizens of the United States and eliminate race prejudice. The mission of the NAACP echoed the focus of Du Bois' Niagara Movement for civil rights, aimed at securing the rights guaranteed in the 13th, 14th, and 15th Amendments, promising an end to slavery, equal protection of the law, and universal adult male suffrage, respectively. Based on the information and the work that the NAACP focused on, particularly challenging segregation in education, the correct answer to the student's question is to C) Achieve racial integration.
During the 1954-1965 Civil Rights era, the NAACP concentrated efforts on overturning Jim Crow laws, notably succeeding in the historic Brown v. Board of Education case, which was a monumental step towards desegregation of public schools and other public facilities. Legislation such as the 1964 Civil Rights Act furthered these goals, thanks to the groundwork laid by the NAACP and other grassroots activists striving for racial equality.
