Residential areas surrounding a city where shops and businesses moved to the suburbs.

• A. Urban growth boundary
• B. Suburbs
• C. Vertical Geography
• D. Zones of Abandonment

Answer: (B)

Suburbs are the outlying residential areas around a city. When shops and businesses relocate from the central city to these surrounding areas, retail and services follow the growing residential zones, creating commercial corridors, malls, and local business districts within the outskirts. This pattern—retail and employment spreading outward with housing—characterizes suburbanization, and explains why the description points to the suburbs themselves. The other terms don’t fit: an urban growth boundary is a planning tool to limit expansion, not a description of where people live and shop; vertical geography isn’t about where development occurs; zones of abandonment refer to areas that have fallen into decline, not the relocation of commerce to the suburbs.
