Indicate residential areas on the aerial photograph below:

Residential areas typically feature a dense pattern of individual houses or apartment buildings, often with distinct roofs, smaller plots of land, and a network of streets. They are usually interspersed with green spaces like gardens and parks. In contrast, industrial areas have large, often rectangular buildings (warehouses, factories), commercial areas have larger buildings (shops, offices) along main roads, and natural areas consist of vegetation, water bodies, or undeveloped land.

• A: This appears to be a river or estuary, a natural water body.
• B: This is the coastline, consisting of a beach and the ocean.
• C: This area shows large, uniformly shaped buildings with extensive parking lots or open spaces, characteristic of industrial or large commercial complexes.
• D: This area displays a high density of smaller, individual structures with varied rooflines, arranged along a clear street grid, and surrounded by trees and green patches. This pattern is typical of a residential neighborhood.
• F: This area features large, manicured green spaces with specific layouts, indicative of a golf course or large park, possibly with some larger institutional buildings.
• G: This is the open ocean.

Based on the visual characteristics, area D clearly shows the typical layout and building density of a residential neighborhood.

The residential area on the aerial photograph is indicated by: $\boxed{\text{D}}$
