How may the uploaded floorplans differ from preloaded ones?

The selected answer is correct because uploaded floorplans created by users can vary significantly in terms of scale. Unlike preloaded floorplans, which are typically standardized and adhere to certain scaling guidelines, user-uploaded floorplans may not maintain the same proportionate dimensions. This discrepancy can arise from the user’s design software or technique, leading to different interpretations of space and layout.

In contrast, the other options suggest specific attributes that do not universally apply to uploaded floorplans. For instance, uploaded floorplans are not guaranteed to be more detailed; they can be simpler than preloaded versions depending on user preference. Similarly, while some users may choose to create square layouts, there is no requirement that all uploaded plans have to adhere to this geometric limitation. Lastly, including furnishings is not mandatory for every uploaded floorplan, as some users may choose to represent empty spaces or focus solely on structural attributes.
