For minors, what is the maximum number of hours they are allowed to work per day on a school week?

The correct choice reflects the regulations set forth concerning minors' work hours during school weeks, specifically designed to ensure that their education is prioritized. For minors, the legal maximum number of hours they can work in a single day during a school week is indeed limited to 4 hours. This regulation is in place to safeguard their well-being and ensure they have sufficient time for school and study.

It is important to adhere to these labor laws to promote a balanced approach that allows minors to gain work experience without compromising their education. The other options do not align with the established legal limits and reflect misunderstandings of the rules governing youth employment.
