Concept:A traverse is classified based on whether it forms a closed figure or connects two known reference stations.
Explanation:When a traverse begins and ends at the same point, it forms a closed loop.
Also, when a traverse connects two separate stations whose coordinates are already known, it is treated as a closed traverse.
This is because the surveyor can check and adjust the measurements using the known positions at both ends.
An open traverse, on the other hand, does not return to a known station or close on a second known point.
Therefore, the traverse described in the question is a closed traverse.
Answer:A. closed traverse
