Which term describes an informative call that does not establish a boundary?

The term that describes an informative call that does not establish a boundary is "C. Passing/Descriptive Call." In land surveying, descriptive calls provide additional information about the land or property being surveyed without defining the precise boundaries. They may refer to natural features, nearby landmarks, or other characteristics that provide context but do not legally establish where the boundaries of the property lie.

Understanding this term is important for land surveyors, as it helps in interpreting survey descriptions and communicating property characteristics accurately. Utilizing descriptive calls can assist in visualizing a parcel's location and context, which is crucial in land development or property disputes. The other terms, such as deficiency, excess, and bounds, tend to refer more directly to aspects of boundary definition or measurements rather than providing contextual or supplementary information.
