The correct answer is (a) Kerala.
Kerala has the highest urbanization rate in India, with 55.3% of its population living in urban areas. This is followed by Maharashtra (45.3%), Tamil Nadu (44.8%), and West Bengal (38.6%).
Kerala’s high urbanization rate is due to a number of factors, including its relatively small size, its high literacy rate, and its strong economy. The state has a long history of migration from rural to urban areas, and this trend has continued in recent years.
Kerala’s urbanization has brought both benefits and challenges. On the one hand, it has led to economic growth and development. The state has a thriving manufacturing sector, and its service sector is also growing rapidly. Urbanization has also made it easier for people to access education, healthcare, and other services.
On the other hand, Kerala’s urbanization has also led to problems such as traffic congestion, pollution, and crime. The state is struggling to provide adequate housing and infrastructure for its growing population.
Despite these challenges, Kerala’s urbanization is likely to continue in the future. The state’s economy is expected to grow, and its population is expected to continue to increase. This will put further pressure on the state’s infrastructure and resources.
The other options are incorrect because they have lower urbanization rates than Kerala. Maharashtra has a urbanization rate of 45.3%, Tamil Nadu has a urbanization rate of 44.8%, and West Bengal has a urbanization rate of 38.6%.
