Which example best identifies a birthright citizen of the United States?(1 point)

A. a migrant who is a lawful permanent resident of the U.S.
B. a child born in another country to a permanent resident of that country
C. a person who was born in another country to citizens of that country, but who has lived continuously in the U.S. for more than 5 years
D. a child born in the U.S. to undocumented parents

D. a child born in the U.S. to undocumented parents

The example that best identifies a birthright citizen of the United States is option D: a child born in the U.S. to undocumented parents.

To determine the correct answer in this multiple-choice question, we need to understand the concept of a birthright citizen of the United States. A birthright citizen is someone who acquires citizenship of a country by being born there. In the case of the United States, anyone born within its territories, regardless of the immigration status of their parents, is considered a U.S. citizen.

Now, let's go through each option:

A. A migrant who is a lawful permanent resident of the U.S. - This individual is not considered a birthright citizen since they acquired their residency through the immigration process, rather than being born in the United States.

B. A child born in another country to a permanent resident of that country - This child would be considered a citizen of the country where they were born, not a birthright citizen of the United States.

C. A person who was born in another country to citizens of that country but has lived continuously in the U.S. for more than 5 years - This person, although having lived in the United States for an extended period, is not a birthright citizen since they were not born within U.S. borders.

D. A child born in the U.S. to undocumented parents - This child is indeed an example of a birthright citizen of the United States. Regardless of the parents' immigration status, if a child is born within U.S. territory, they automatically acquire U.S. citizenship.

Therefore, the correct answer would be D, a child born in the U.S. to undocumented parents.
