Which statement best describes a problem facing children working in industrial jobs during the late 19th and early 20th centuries

Children as young as six years old during the industrial revolution worked hard hours for little or no pay. Children sometimes worked up to 19 hours a day, with a one-hour total break. This was a little bit on the extreme, but it was not common for children who worked in factories to work 12-14 hours with the same minimal breaks. Not only were these children subject to long hours, but also, they were in horrible conditions.
