The choice identifying the extensive grid system of Chang'an is significant because it highlights the advanced urban planning and organization of the city during the Tang dynasty. Chang'an was one of the largest and most cosmopolitan cities of its time, and its layout featured well-defined streets that formed a grid pattern. This design facilitated efficient movement and navigation, accommodating the city’s heavy traffic, including pedestrians, carts, and merchants.

Additionally, this grid system allowed for clearly designated spaces for different functions, such as markets, residential areas, and administrative buildings, which contributed to the city's ability to manage a large population and foster trade and cultural exchange. The urban layout of Chang'an was reflective of its importance as a political, economic, and cultural center along the Silk Road, further establishing its legacy in city planning.

While the other options deal with significant aspects of urban infrastructure and development, they do not encapsulate the unique and essential aspect of Chang'an’s city design as effectively as the grid system does.
