Yes, the correct answer is D. Cities marked off separate zones for heavy industry, financial institutions, residences, and public spaces. The development of mass transit systems in American cities led to the creation of zoning regulations. These regulations allowed for the separation of different land uses within the city, such as residential, commercial, industrial, and public spaces. This helped to organize and control the growth of cities, as well as promote efficiency and safety in urban planning.

The correct answer is D. Cities marked off separate zones for heavy industry, financial institutions, residences, and public spaces.

Mass transit had a significant effect on American cities by contributing to the development of urban planning and zoning. As transportation improved through the use of mass transit systems, such as streetcars and subways, cities underwent a transformation in terms of how they were organized and structured.

With the arrival of mass transit, cities started to mark off separate zones for different uses. This was known as zoning. For example, heavy industrial areas would be located in one zone, financial institutions in another, residential areas in another, and public spaces in yet another. This zoning allowed for more efficient and organized urban development.

By designating specific areas for different activities, cities were able to better manage things like noise, pollution, and traffic congestion. Zoning also helped to reduce conflicts between different types of land use, such as industrial and residential areas. Additionally, it allowed for more efficient land use and resource allocation.

So, in summary, one effect of mass transit on American cities was the establishment of separate zones for heavy industry, financial institutions, residences, and public spaces (option D).
