Answer:
Option D, Africa American migrants to northern cities.
Step-by-step explanation:
African American migrants to northern cities would have been most likely to oppose the National Origins Act of 1924. The act aimed to restrict immigration to the United States by establishing quotas based on the nationality of the immigrant's country of origin. African Americans, who were already facing discrimination and segregation in the United States, would have been sensitive to the issues of exclusion and discrimination. They also would have likely sympathized with immigrants who were facing similar struggles. Additionally, African Americans in northern cities were part of a larger movement for civil rights and equality, which included advocating for the rights of immigrants and opposing discriminatory laws.
