Final answer:
The Bureau of Labor Statistics calls people who have stopped looking for a job after previously seeking work 'discouraged workers.' They are part of the 'hidden unemployment' and are not counted as part of the active workforce. The correct answer is option B.
Step-by-step explanation:
The term used by the Bureau of Labor Statistics to describe people who once sought work but have given up looking for a job is B. discouraged workers. These individuals may have been actively looking for employment in the past, but due to a variety of reasons, such as not finding suitable work after a lengthy search, they have stopped looking and are not currently counted as part of the active workforce. This concept falls under the broader category of hidden unemployment, which also includes those in part-time or temporary positions seeking full-time work, and those who are underemployed, meaning they are working in lower-paying jobs or jobs that do not utilize their skills effectively.
