The main idea is that a parcel is defined within a single site. In Civil 3D, a site serves as the data container and context for parcel boundaries. All segments that make up a parcel boundary must belong to the same site so the software can reference a common coordinate system, property context, and boundary data. If parcel segments come from different sites, they belong to separate geographies and data contexts, so they can’t be combined into one continuous parcel boundary. That’s why the statement is true.

The other options aren’t how Civil 3D organizes parcel data: a parcel isn’t defined by city boundaries, and the system prohibits forming a single parcel from segments that span multiple sites.
