The correct answer is C) industrial jobs.
An important pull factor for immigrants who arrived at the US in the 1800s were industrial jobs.
Industrialization detonated employment opportunities for many people in America. New factories established in larger cities that rapidly became populated by people that used to live in the rural areas of the country. They were not the only ones that searched for better economic opportunities. Migrant did it too. Many immigrants from Europe considered that the industries in The United States were the solution to their problems. Factories of the time did not require very skilled workers so talent was not an issue. So people from Eastern Europe and from Asia started to arrive through the migration facilities in Ellis Island, New York, and later, through Angel Island, in San Francisco, California.
