Answer:
The correct answer is option D.
Explanation:
The unemployment rate shows the number of people who are unemployed. It is the ratio of the number of people unemployed and the total labor force.
The discouraged workers are those people who are not employed and are not actively looking for jobs because they were not able to find one and stopped looking.
In the official statistics, the discouraged workers are not included in either labor force or unemployed persons. This may lead to an underestimation of the amount of unemployment.
