Answer:D. a discouraged worker.
Step-by-step explanation:
What is a Discouraged Worker?
A discouraged worker is an individual who has given up looking for employment eventhough they are perfectly eligible to hold down a job but since they have repeatedly tried to look for employment but have failed constantly to find one for atleast 4 weeks they have then ceased their search. Discouraged workers have stopped looking for employment opportunities because they aren't any jobs available that suits their qualifications or haven't received any offer even after constantly applying.
Since they have stopped searching they are not included in the labor force hence when we see the statistics for unemployment these people are not included there.
People have different reasons that make them become discouraged such as lack of skills to adapt In an evolving technological demanding work environment.
