Letter D is the correct answer.
The Industrial Period, in Great Britain, was a period of major capitalism, machine development, and factory growth. In this period, people decide to move from the farms to the city in order to work and get a higher income. However, the working conditions of factory workers were not the ideal: they were exposed to long hours of work, low remuneration, and insalubrity. Also, during the early stages of the Industrial Revolution, factory managers were generally harsh and abusive to workers.
