Final answer:
The correct answer is option B. None of the provided options accurately describe the 1864 Act to Encourage Immigration. However, the National Origins Act of 1924 introduced significant restrictions on immigration, establishing quotas based on national origins from the 1890 census and effectively banning immigration from Asia.
Step-by-step explanation:
The 1864 Act to Encourage Immigration is not the correct legislation related to the options given, as the significance of the policies mentioned are associated with the early 20th century and not 1864. However, regarding immigration policies in the United States, the National Origins Act of 1924 is notable.
This Act aimed to curb immigration from central and southern Europe by establishing quotas based on the national origins of immigrants from the 1890 census.
This significantly limited the number of immigrants from southern and eastern Europe. The Act also included a provision that effectively banned immigration of Asians, as it barred any group who was ineligible for U.S. citizenship, a status then denied to most Asian nationalities due to existing laws.
In summary, none of the provided options accurately describe the 1864 Act to Encourage Immigration, but if the question intends to refer to the significant immigration policies of the early 20th century, then option C is the most relevant, although it incorrectly dates the establishment of quotas to 1864 instead of the 1920s.
