Answer:
Option A. In the years closely following World War II, many African Americans renewed their efforts to work for civil rights.
Step-by-step explanation:
By the end of World War II, more than 1.2 million African Americans had served the United States in its fight against fascism. But when these soldiers came back home, they found that while their country fought for ideals such as freedom and democracy, inside its own territory black communities were still highly discriminated and segregated. This and other events that occurred at the beginning of the 1950's catapulted what became known as the civil rights movement, where plenty of African Americans devoted their time in order to work for their rights.
