The use of child labor in factories and other industries was very common.
This is the best option. The information in the excerpt indicates that child labor was a big enough problem that a committee was formed to speak out for children's rights. The other options seem less likely because if most business owners found child labor unacceptable it wouldn't be wide-spread enough for a committee to be formed. Also, the excerpt does not state that it's an unacceptable alternative to formal education. While the excerpt does mention that reducing the number of hours children are allowed to work would give them time for school, it doesn't say anything about work being a replacement for education. The reasoning for choosing the first option negates the last one. It's either common or rare.
