Answer:
d) Mary, who was laid off last year and who was looking for a full-time job until last month
Step-by-step explanation:
In the United States, a discouraged worker is defined as a person not in the labor force who wants and is available for a job and who has looked for work sometime in the past 12 months (or since the end of his or her last job if a job was held within the past 12 months), but who is not currently looking because of real or perceived poor employment prospects.
