The correct answer is B) to establish quotas on the number of immigrants from each country who could legally enter the United States.

The best sentence that describes the purpose of the law signed by President Calvin Coolidge is to establish quotas on the number of immigrants from each country who could legally enter the United States.  

The National Origins Act of 1924 restricted the number of immigrants that wanted to enter the United States. The policy was very strict and President Coolidge signed the law because he wanted to maintain isolation after the nation´s experience during World War 1. Many Americans considered that in those years, many uneducated and unskilled immigrants arrived in the United States and took jobs from American people.
