⭕ A. Plane table surveying
⭕ B. Total station surveying
⭕ C. Theodolite traversing
⭕ D. None of the above
📚 Explanation:
In Plane Table Surveying, both field observations and plotting are carried out simultaneously on the site.
🔹 It is a graphical method that eliminates the need for detailed field notes.
🔹 This allows the surveyor to draw the map while directly viewing the terrain, resulting in faster and more intuitive plotting.
🔹 It is ideal for small-scale surveys where high precision is not critical.

Key Points on Plane Table Surveying:
- Graphical method — observations and plotting done in field
- No intermediate field notes required
- Useful for topographic mapping and site planning
- Alidade is used for sighting and drawing
- Not suitable for high-precision or large-scale surveys
