The correct anser to "How did the Industrial Revolution affect the development of social classes in Great Britain?" is b. It divided society into a greater number of social classes.
Before the Industrial Revolution, British society was roughly divided into two major classes: the nobles and the peasants and it was mostly an agrarian society.
However, the Industrial Revolution caused a rapid urbanization and the exodus of many people from the villages to the blooming industrial cities. The work in the factories brought with it the rise of two new social classes: the capitalists who owned the factories, controlled the money and had influence in the government; and the proletariat who worked in the factories, had little money and lived in poor conditions.
There were also members of a middle class such as teachers, doctors or scientists that managed to live in better conditions than the proletarians but did not have the money or political influence of the capitalists and they did not own the means of production.
