The economists would consider John Smith as frictionally unemployed while searching for job in California.
Option A
Explanation:
Frictional unemployment is sometimes also called search unemployment. It can be defined as the time spent between searching for a new job while leaving another job in which a person is still working. This may result due to better opportunities or better salary, or lack of satisfaction from the previous job.
It may take place in a good functioning economy as well, where workers are not satisfied with their work. It is somehow even present in all economies and is a growing concern in today's world, where millennials are never satisfied with their work environment.
