Answer:
The correct answer is C. Exclusion.
Step-by-step explanation:
Nativism is a policy to encourage native inhabitants' interests against immigrants' interests. This policy was established because native people believed that immigrants would distort the natives' cultural values. There were situations in which immigrants outnumbered native inhabitants and in this way, the different native people's movements tried to avoid cultural change.
There were some measures adopted against immigrants in terms of economy, culture and environment. For example, it was said that immigrants acquired jobs that should be given to native people as well as they did not pay the required taxes compared to their services' costs. Another aspect was that immigrants did not learn the language spoken in a specific community.
