A. White Americans felt economically threatened by the immigrant workers from China is the correct answer.

Explanation:

The Chinese people faced racism and discrimination since they first arrived in US during Gold Rush and legislations were used against them. The first such legislation was the Foreign Miner License Tax Law enacted in 1850. They were categorized with Blacks and Indians and were denied the right to testify against white men. The hostilities heightened against the Chinese during the economic downturn of 1870's because labor union leaders considered them to be responsible for unemployment and depression in wages. They also used to consider them morally corrupt. Due to these hostilities local and statewide restrictions were enforced against them and they were permanently barred from entering united states by the Chinese Exclusion Act of 1882.

du boi was considered a radical because he wanted the immediate end for segregation. the biggest different between him and booker t. washington is that, even though washington believed that segregation should be considered illegal, he did not believe at all that a law was needed to keep blacks away from whites and that this would be something natural (to have the races apart) for a long time until society adjusted, while du boi believe that agitation was the only way to end segregation.
