The correct answer is B) Were designed to protect the rights of African Americans.
During Reconstruction, there were three critical constitutional amendments that were meant to help African Americans. These include:
1) 13th amendment- This constitutional amendment gets rid of slavery in the United States, officially freeing millions of slaves.
2) 14th amendment- This amendment states that all people born on US soil are US citizens. It also established the Equal protection clause to ensure that all citizens are treated equally under the law.
3) 15th amendment- This amendment said that a person cannot be stopped from voting based on their race, essentially giving African-American males the right to vote.
