Which constitutional amendment is described as defining citizenship, granting citizenship to former slaves, and defining voters as males at least 21 years of age?

• A. 14th Amendment
• B. 15th Amendment
• C. 19th Amendment
• D. 1st Amendment

Answer: (A)

The main idea here is how the Fourteenth Amendment reshaped who counts as a citizen and how voting was tied to citizenship after the Civil War. It defines citizenship by birth in the United States or through naturalization, extending that status to former slaves and ensuring those citizens are protected under due process and equal protection. It also links voting power to citizenship by including a provision that reduces a state's representation in Congress if it denies the right to vote to male citizens 21 years of age or older. This combination—establishing citizenship for formerly enslaved people and tying voting rights to male citizens aged 21+—is what the amendment does in this context.

The other amendments don’t fit this combination. The Fifteenth Amendment bars denying the right to vote based on race or previous condition of servitude but doesn’t redefine citizenship or set age and gender voting rules. The Nineteenth guarantees women’s suffrage, not citizenship definitions. The First Amendment protects freedoms like speech and religion, not citizenship or voting rights.
