Which of the following statements about the 14th Amendment is true?

The 14th Amendment, ratified in 1868, plays a crucial role in American constitutional law, particularly regarding citizenship and equal protection under the law. The statement about the 14th Amendment being true, specifically that it grants citizenship, refers to Section 1, which states that all persons born or naturalized in the United States are citizens of the United States and of the state wherein they reside. This provision was particularly significant in the aftermath of the Civil War, as it ensured that formerly enslaved individuals were recognized as citizens, affirming their rights under the Constitution.

The other options do not accurately reflect the specific provisions of the 14th Amendment. While the amendment does address issues related to voting rights in later sections, it doesn't directly grant the right to vote, which is more specifically addressed in the 15th Amendment. Additionally, it does not abolish slavery—that was achieved through the 13th Amendment. Lastly, the 14th Amendment does not restrict freedom of speech; such rights are more closely connected to the First Amendment. Therefore, the significance of the 14th Amendment lies specifically in its guarantee of citizenship and the protections it extends to all citizens.
