Explanation:

- First stage: This is the initial phase of urbanization, where rural areas start to see some urban development. Growth is slow as the economy begins to shift from agriculture to industry.

- Second stage: Known as the acceleration stage, this is when urbanization rapidly picks up pace. Migration from rural to urban areas increases significantly, driven by industrialization and better economic opportunities. The urban population grows quickly.

Correct Answer: Second stage

- Third stage: In this stage, urbanization continues but at a slower rate. The pace stabilizes as the majority of the population is already urban or moving towards urban settings.

- Fourth stage: This stage is characterized by urban saturation and possible suburbanization. Growth in urban centers stabilizes or even declines as people move to suburban areas or smaller towns.
