Answer:
C. The lower-classes created factories to increase production.

Both men and women works in the factories in order to feed their family which leads to increase in the production of goods in the factories. Without lower class workers, the increase in the production of goods will not be possible so that's why we can conclude that lower class workers are necessary for production of goods.
