Answer:
all persons who were born and naturalized in the U.S.A.
Step-by-step explanation:
Under Section 1 of the 14th Amendment, those who will be considered citizens of the United States are those who have been born and naturalized in the country. This means whatever color the person has, especially those who were former slaves. Many of these slaves were freed after the American Civil War, thus, it became important to classify them as citizens of the country. This means, they, too, are subject to have an equal protection under the law.
