Which of the following was a result of nativism in the United States?

A. Decline of the racist organization Klu Klux Klan.

B. The decision to stay out of the League of Nations.

C. Laws that limited immigration by nationality.

D. New laws that encouraged European immigration.

The answer is C. Laws that limited immigration by nationality.

Nativism is the majority's interest over immigrants. The majority did not like immigrants coming into their country so they made laws related to limiting immigrant's access.

It is not A because the Klu Klux Klan flourished as a result of nativity. Many white men hated black people and supported the beliefs of the Klu Klux Klan. In only declined later.
