Which law described in “kids at work” prevents sophie in “rocks in my pocket” from getting a work permit?

C. the 1916 federal child labor law

Explanation:

The "1916 Federal Child Labor Law" was also known as the "Keating-Owen Child Labor Act of 1916." This means that children under age 14 will not be employed. Those who were aged 14 to 18, on the other hand, will only have to work for eight hours and not longer. Such law can be seen in the story entitled "Rocks in my Pocket." Although Sophie wanted to work at the coat factory, she couldn't get a work permit because she was too young and it wasn't allowed.

So, this explains the answer.
