The correct answer is C) competition in the workplace.
The reason that caused anti-immigrant sentiment to increase in the US in the 1800s was competition in the workplace.
Immigrant left their native countries because they suffered from persecution, or they lacked opportunities to grow and prosper. They considered that America was the best place to try new things or start a new life. Thousands of immigrant arrived in the United States in the 1800s. They were desperate to find a job and accepted most kind of jobs at low wages. White Americans protested because they thought that immigrants took jobs that belonged to them and this created an anti-immigrant sentiment in the United States.
