Which amendment defines citizenship and guarantees equal protection under the law?

• A. Citizenship and equal protection
• B. Voting rights
• C. Abolition of slavery
• D. Right to own land

Answer: (A)

This is about the amendment that defines who is a citizen and protects everyone under the law equally. The Citizenship Clause explains that all people born or naturalized in the United States are citizens, which extended national membership beyond any previous status. The Equal Protection Clause then requires states to treat people in similar situations the same way, preventing laws from singling out groups for unfair treatment. Together, these provisions ensure both who is counted as a citizen and that laws apply to all people fairly, which is why this amendment is the best answer. The other options point to different topics—abolishing slavery, voting rights, or land ownership—not to citizenship status or equal protection.
