Final answer:
The Fourteenth Amendment guarantees in the Bill of Rights were applied to state actions.
Step-by-step explanation:
The answer to the question is option b. Guarantees in the Bill of Rights were applied to state actions.
The Fourteenth Amendment to the United States Constitution established important guarantees for individuals in the states. One of the key provisions of this amendment is the Due Process Clause, which states that no state shall deprive any person of life, liberty, or property without due process of law. This clause allowed the Supreme Court to extend the protections of the Bill of Rights to state actions, ensuring that individuals in the states have the same constitutional rights as those protected by the federal government.
By applying the Bill of Rights to state actions, the Fourteenth Amendment helped to protect the civil rights and liberties of all citizens and ensure equal protection under the law.
