What of the following statements is true about the 13th 14th and 15th amendments to the Constitution and their impact after the Reconstruction Era ended?

The 13th, 14th, and 15th Amendments, known as the Reconstruction Amendments, aimed to establish rights for formerly enslaved people after the Civil War. The 13th Amendment abolished slavery, the 14th guaranteed citizenship and equal protection under the law, and the 15th aimed to secure voting rights regardless of race. However, after the Reconstruction Era ended, many Southern states implemented Jim Crow laws that effectively circumvented these protections, leading to widespread disenfranchisement and discrimination against African Americans. Thus, while the amendments were significant in theory, their enforcement was severely undermined in practice.
