Answer:
C. Danny, who works one hour a week at his parents´ salon.
Step-by-step explanation:
The labor force is described as the number of people who is actually under a labor relationship or those who are unemployed but are on the active look for a job.
The last group is where Ryan entered because he is unemployed but is looking for Jobs. On the other hand, Danny is currently working but only an hour a week and at his parents´ salon, probably he does not receive a salary and has not signed a contract to work there. That is the reason why he wouldn´t be counted in the labor force.
I hope this answer helps you.
