Step-by-step explanation:
The term which refers to a person who favors U.S.-born citizens and discriminates against immigrants is c) Nativist.
Nativism is known for prizing White Americans with older family trees over more recent immigrants, while rejecting outside influences in favor of their own local customs. Nativists were often against immigrants who they perceived to be a threat to the social and cultural fabric of the nation. In history, nativism has led to various discriminatory practices and policies, as seen with legislative acts and movements that sought to restrict immigration, particularly from non-white and non-Protestant populations.
Ironically, these same nativists also harbored prejudices against Native Americans who were not part of their idealized vision of a white, Anglo-Saxon, and Protestant America. The American Protective Association, for example, was a nativist organization aimed at curbing immigration and was influential in the passing of exclusionary laws like the Chinese Exclusion Act and the Immigration Act of 1924.
