Final answer:
The FLSA sets work hour restrictions for children aged 14 and 15 years old (option a) and 16 and 17 years old (option b).
Step-by-step explanation:
The Fair Labor Standards Act (FLSA) establishes the minimum wage, limits on child labor, and rules requiring payment of overtime pay for those in jobs that are paid by the hour and exceed 40 hours per week. When it comes to minor age group work hour restrictions, the FLSA sets restrictions for children aged 14 and 15 years old (option a) and 16 and 17 years old (option b). Children aged 13 and 14 years old (option c) and 17 and 18 years old (option d) are not included in the FLSA work hour restrictions.
