Answer: A. they gain new legal rights
Explanation:
As a result of the American Civil War, African Americans gained freedom from slavery in all states that had been allowing slavery. The newfound freedom meant that they were now free American and could apply for jobs they wanted instead of jobs that their masters chose for them.
Being able to do their own jobs, they were able to make an income which goes a long way in economic emancipation. Even though they now had legal rights, it took several decades for them to be treated equally in work places due to the Civil Rights movements of the 20th century.
