The correct answer is b.urged to leave and found it difficult to make a living.
Explanation:
As a result of the Dust Bowl, most "Okies" who headed to California were urged to leave and found it difficult to make a living. "Okies" was the term used to describe the hundreds of thousands of people who fled Oklahoma and moved to Southern California to try and find new opportunities. They were mainly greeted with signs that said to "Get Out" and found it difficult to meet their basic needs. This difficult time period is best epitomized in the novel "The Grapes of Wrath" by John Steinbeck.
