What type of areas are surveyed in the practice of land surveying?

Land surveying encompasses a broad range of activities that includes the measurement and mapping of both natural and man-made features across diverse environments. This practice is essential for various applications such as construction, land development, resource management, and environmental protection. In the context of land surveying, areas surveyed can include urban settings, agricultural lands, forests, wetlands, mountains, and waterfronts, making option C the most accurate choice.

The inclusion of both natural features (like rivers, hills, and forests) and man-made features (such as roads, buildings, and property lines) provides a comprehensive view of the terrain and is crucial for effective planning and development. Each of these environments presents unique challenges and requirements, necessitating a thorough understanding of surveying principles to capture accurate data.

Other options narrow the focus too much, which fails to represent the true scope of land surveying. Urban locations, agricultural areas, and residential properties are just specific contexts within the wider field, not exclusive areas for surveying. Thus, C stands out as it accurately reflects the comprehensive nature of land surveying practice.
