Option A is the right answer.

Urbanization refers to the shift in population from the rural areas to the urban. Numerous factors were responsible for the growth of cities including the growth of factories, the need for jobs and the immigrants. When workers found more work in the cities their purchasing power began to grow. This, therefore, led to the improvement in the lifestyle of people in the cities.
