Which statement best describes how urbanization in petroleum-rich states differs from urbanization in states without fossil fuel wealth?

A. In fossil fuel-rich countries, cities are unequipped to handle an influx of migrant workers because they are ancient cities. In countries without fossil fuel wealth, the population has not undergone significant urbanization.

B. In fossil fuel-rich countries, populations in cities are primarily long-term immigrants seeking citizenship. In countries without fossil fuel wealth, there have been lavish building booms to create global tourist destinations.

C. In fossil fuel-rich countries, populations are largely rural because of agricultural production areas. In countries without fossil fuel wealth, there are massive flows of migrant guest workers into cities.

D. In fossil fuel-rich countries, populations are more urbanized and cities have undertaken lavish building booms. In countries without fossil fuel wealth, there are massive flows of poor rural migrants into cities.
