The Correct Option is B

Solution and Explanation


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.
