Concept:In surveying, a closed traverse is expected to return exactly to its starting point. When it does not, the resulting gap is called the error of closure.
Explanation:A closed traverse begins and ends at the same reference point.
Due to small mistakes in measuring distances, angles, or directions, the plotted end point may not coincide with the point of origin.
The linear distance between the computed final position and the original starting point is known as the closing error.
This error is only detected when the field measurements are plotted or computed.
The other options are not correct: an error of compass affects bearings, but the specific failure described is the terminal misclosure of the traverse.
Field error is a general term, and traverse error is not the standard name for this misclosure.
Answer:C. Error of closure
