Answer:
b. Fourteenth
Explanation:
This is the text of section 1 of the Fourteenth Amendment to the Constitution of the United States:
Section. 1. All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
In this section, we see that the Constitution mandates equal rights for all people born or naturalized in the United States. However, more importantly, this amendment prohibits state interference in the exercise of these rights. It tells us that no state can make or enforce any law that makes it impossible for Americans to enjoy the privileges and immunities that the Constitution grants them.
