⭕ A. Resection
⭕ B. Orientation
⭕ C. Orientation and resection
⭕ D. None of these
📚 Explanation:
The two-point problem and three-point problem are classical surveying methods used for both orientation and resection.
🔹 Resection determines the position of the instrument by measuring angles or directions to known points.
🔹 Orientation refers to aligning the survey to a known reference direction or baseline.
🔹 These methods help establish the location and alignment of the instrument station relative to known points.

👉 Therefore, the correct answer is: C. Orientation and resection
Key Features of Two-point and Three-point Problems:
- Used to determine both instrument position and orientation
- Involve measuring angles to known reference points
- Combine principles of orientation and resection in surveying
- Commonly applied in plane table and theodolite surveying
- Assist in establishing accurate survey control stations
