What type of plan shows the location of a structure in relation to nearby features like roads and other buildings?

The correct choice is a site plan, as it specifically illustrates the location of a structure in relation to surrounding features, including roads and other buildings. A site plan provides a comprehensive view of the land and helps in understanding how the structure interacts with its environment, such as access points, landscaping, and property boundaries.

In contrast, a floor plan focuses on the internal layout of a building, detailing room configurations, windows, and doors but does not address external features relative to the structure. An elevation plan serves to show how a building looks from the outside, providing details about its height and architectural style without contextualizing its location in relation to other nearby features. Meanwhile, a plot typically refers to the parcel of land itself and does not provide the required relational context of the building to its surroundings.

Thus, a site plan is the most appropriate and effective tool for understanding the spatial relationship between a structure and other environmental features.
