Which of the following best illustrates the integration of climate resilience in the development of smart cities?

A smart city that uses sensor networks to monitor weather, air quality, and water levels, then automatically adjusts traffic signals, water‑management systems, and energy grids, best shows climate resilience. By collecting real‑time data, the city can predict heat waves, redirect traffic to reduce emissions, and trigger green‑roof rain‑water harvesting when storms are forecasted. This approach blends technology, planning, and environmental design to protect residents while reducing the city’s carbon footprint. For example, Singapore’s Smart Nation program uses sensors to manage heat, flood risk, and energy use, making the city more resilient to climate change.
