The correct answer is B) model factory town.
A model factory town had factory owners housing and protecting their female employees.
For instance, that is the case of Lowell, Massachusetts, considered to be the origin of the United States Industrial Revolution because many textile mills were located in this city. By the 1850s, the city of Lowell hosted many factories that produced cotton. It was Francis Cabot Lowell who designed a system of production where manufacturing was done in one roof and the workers were young women.
