Answer:
e. Samantha, who quits her job to look for a better one
Explanation:
This is a topic in economics and business that seeks to test your understanding of business cycles. This particular question is on frictional unemployment.
The main feature of frictional unemployment is that there is someone or a group of people who are actively looking for work. They remain unemployed until they find work.
The other answers in the question point to people who are not looking for work and thus do not make up part of the frictionally unemployed population group.
E.g Sylvia quit her job to spend more time with the kids, the college student who quit work to return to school etc... all these are not actively looking for job.
I hope this helps you understand the question better and you can solve similar questions
