Answer:
Option: A. Urban workers' wages were very low and made it difficult to live.
Explanation:
During the industrialization, the factory workers were the major suffers. Their living condition was worse. Workers forced to work for long shifts in closed rooms where the air was not breathable. Wages were low because people were willing to do work as long as they got paid. Factory owners took advantage of their condition and exploited them. Low wages made their living condition more dangerous because they could not afford to live in a decent house when they have to feed the entire family.
