Option B

Explanation:

The rapid travel on interstate highway helped Texas's population to move to suburbs. This also caused sub-urbanization of Texas. The people from urban places shifted to suburb areas because of easy means to move to the suburban areas.

The urban population shifted because of lack of places for houses or for employment purposes. Most people also do not find enough green places in the urban areas which is why they shift to suburbs.
