What does land-use efficiency aim to achieve in urban planning?

Land-use efficiency in urban planning seeks to optimize land development to minimize waste, which is why this answer is correct. This concept emphasizes the importance of using land in a manner that maximizes its potential and functionality while reducing unnecessary consumption of resources. Efficient land use integrates various elements such as residential, commercial, and recreational spaces in a way that serves the community's needs without overwhelming the land or the infrastructure.

The goal is to create compact, well-planned urban areas that improve accessibility, reduce transportation costs, and enhance the quality of life for residents. By optimizing land use, urban planners can make better use of existing infrastructure, preserve green spaces, and promote sustainable development.

Other options do not capture the broader aim of land-use efficiency as effectively. For example, focusing only on maximizing residential areas or commercial development does not take into account the mixed-use aspects that enhance community vibrancy and sustainability. Similarly, while minimizing urban sprawl is an important goal related to land-use efficiency, it is more of a strategy rather than the core objective of optimizing land development itself.
