Answer:
D. joined organizations dedicated to fighting segregation.
Step-by-step explanation:
During World War II, many African American citizens enlisted to fight in the war. However, despite their efforts and bravery, they were still treated like second-class citizens. Their quotas were lower, and when they did manage to enlist, they were segregated from others and for the most part appreciated less. This led to a rise in African Americans who joined organizations dedicated to fighting segregation and achieving equality both within the troops and in society at large.
