The most accurate response is:
The clauses included in the Fourteenth Amendment were not enforced or interpreted consistently by the Supreme Court.
This statement highlights the limitations of the Fourteenth Amendment in the years following its ratification, as the Supreme Court often failed to uphold its protections, particularly in cases involving the rights of African Americans and other marginalized groups. This inconsistency in enforcement and interpretation contributed to the amendment being seen as unsuccessful in achieving its original goals of ensuring equal protection and due process under the law.
