The correct answer is option "D": expanded civil liberties.
The fourteenth amendment to the U.S. Constitution (1868), granted citizenship to all people born or naturalized in the United States equal protection of the laws. Not only did the 14th amendment grant citizenship but also extended liberties and rights by the Bill of Rights to former slaves. Consequently, those African Americans and slaves who had been emancipated after the American Civil were included under the umbrella phrase “all persons born or naturalized in the United States."
