which if the following transformed city life in the late 1800s?

Without a list of options to choose from, I am unable to provide a specific answer to this social studies question. Please provide me with more information regarding the available options.

To determine which of the following transformed city life in the late 1800s, we need to first identify the "following" or the options you are referring to. If you provide me with the list of options, I can help you analyze them and explain how to arrive at the answer.

The question does not provide a list of options to choose from. Could you please provide the options, so I can assist you further?
