Answer:
The answer is C.
Explanation:
During the Industrial Revolution, throughout the 18th and 19th centuries, child labour became very common in the rising industrial cities. Hiring children was seen as an advantage for production as they were paid less than adults, estimates show that they were paid 20% of the salary of an adult, and they would do the same amount of work.
Child labour was not regulated by any law and chidren's rights were not protected, therefore it became very common and it was not seen as exploitation.
