A discouraged worker is one who:

A) is underqualified for his current job.
B) dislikes his current job but is afraid to quit.
C) drops out of the labor force because he cannot find a job.
D) quits his job because the possibility of advancement was very low.
E) is overqualified for his current job.

A discouraged worker is someone who has dropped out of the labor force because they have become discouraged and believe there are no job opportunities available for them. They are not actively seeking employment but are still capable and willing to work. This can be due to a variety of reasons such as a lack of job openings in their field, not having the necessary qualifications or skills for available jobs, or repeated rejections from past job applications.
