Answer :
Answer: D, A 17 year old high school student who is actively applying for part-time work after school
Explanation:
Persons who are neither employed nor unemployed are not in the labor force. This category includes retired persons, students, those taking care of children or other family members, and others who are neither working nor seeking work. The high school student is actively looking for work, so therefore they are considered unemployed, and would be part of the labor force (and thus, included in the calculation of the unempoyment rate). Thus, the answer is the 17 year old high school student who is actively applying for part-time work after school.
