Answer;

A. cities spread out into the existing countryside

Explanation;

Urban sprawl is the rapid expansion of the geographic extent of cities and towns, often characterized by low-density residential housing, single-use zoning, and increased reliance on the private automobile for transportation.

It is caused in part by the need to accommodate a rising urban population; however, in many metropolitan areas it results from a desire for increased living space and other residential amenities.

The end result is  increased energy use, pollution, and traffic congestion and a decline in community distinctiveness and cohesiveness.
