Answer:
The correct answer must be A)
Step-by-step explanation:
The fourteenth amendment was adopted in 1868, after the end of the civil war. Amendment 13 abolished slavery in 1865, while Amendment 14 resolved the citizenship issue of former freed slaves born in the United States.
Previous Supreme Court decisions, such as the "Dred Scott v. Sandford" case in 1857, determined that African Americans could never be U.S. citizens. The 14th Amendment invalidated that argument.
