Answer:
D) Shift of population to urban centers
Explanation:
The changeover to an industrialized economy led to a "Shift of population to urban centers."
The industrialized economy results from industrialization, whereby most production involves applying machines to produce goods massively. This production process leads to factory settings where people were employed. This situation, in turn, led to urbanization and expanded the production and consumption of goods.
Hence, people moved from rural areas to urban areas for jobs and better lives.
