The correct answer is (d), 2010.
The world’s urban population surpassed its rural population in 2010. This means that more people now live in cities than in rural areas. This is a significant change, as it has been the case for most of human history that more people lived in rural areas than in cities.
There are a number of reasons for this change. One reason is that the world’s population has been growing rapidly in recent decades. This growth has been concentrated in cities, as people have moved from rural areas in search of better opportunities. Another reason is that cities have become more attractive places to live. They offer a wider range of jobs, amenities, and cultural activities than rural areas.
The growth of the world’s urban population has a number of implications. One implication is that cities are becoming increasingly crowded. This can lead to problems such as traffic congestion, pollution, and crime. Another implication is that cities are becoming more diverse. People from all over the world are moving to cities, which can lead to cultural clashes and social tensions.
The growth of the world’s urban population is a complex issue with no easy solutions. However, it is an issue that needs to be addressed, as it has the potential to have a significant impact on the future of humanity.
