Final answer:
The Workmen's Party harbored prejudice against Chinese immigrants out of fear of job competition. Anti-Chinese sentiment led to the Chinese Exclusion Act of 1882, supported by groups like the Asiatic Exclusion League, demonstrating widespread historical xenophobia in the U.S. Option A is correct.
Step-by-step explanation:
The fear and resentment were echoed by various segments of the American populace during the late nineteenth and early twentieth centuries. Xenophobic and racially motivated sentiments were prevalent, leading to significant political and social backlash against Asian immigrants, particularly the Chinese.
One of the most notable actions resulting from these sentiments was the passage of the Chinese Exclusion Act of 1882, which was the first law in US history to exclude a specific ethnic group from immigration based on race. This act was supported by rhetoric from various anti-Chinese groups and organizations, such as the Asiatic Exclusion League, which advocated for broader exclusion laws that would encompass other Asian nationalities, including Japanese and Korean immigrants.
Hence, the correct option is A.
