Step 1: Concept When a survey line is longer than a single chain or tape, direct measurement becomes difficult because the line might "bend".
Step 2: Meaning To keep the measurement perfectly straight, intermediate points must be placed exactly on the line connecting the two end stations.
Step 3: Analysis This process of aligning intermediate points is called ranging. It can be done by eye (direct ranging) or with instruments like a theodolite (indirect ranging).
Step 4: Conclusion Ranging is the correct term for aligning these intermediate points.
Final Answer: (B)
