The correct answer is the 14th amendment.
The 14th amendment established two critical ideas in American society. One of them is the idea of birthright citizenship. This means that all people born on United States soil are automatically citizens. The second idea was the Equal Protection Clause. This was put in place to ensure all citizens, regardless of race, ethnicity, etc. were treated the same under the law.
This was not the case for Japanese Americans during World War II, as thousands of them were sent into internment camps within the United States. They had committed no crime and were not being treated equally under the law.
