The author's MAIN purpose for including the section "The Background" is likely:

B to illustrate reasons why cities are at greater risk of damage from earthquakes.

This choice reflects a common purpose for background sections, which often provide context and explain the factors contributing to a particular issue, in this case, the risk of earthquake damage in urban areas.
