⭕ A. Two point problem
⭕ B. Intersection
⭕ C. Resection
⭕ D. Radiation
📚 Explanation:
The Two Point Problem is a technique in plane table surveying used to orient the plane table when the table is set up at a station, and two known but inaccessible points are available.
🔹 The method involves measuring angles or directions to two previously plotted and visible points.
🔹 It is most useful when the current station cannot be connected directly to the existing framework.
🔹 It is part of the broader concept of resection but is specifically defined as a two-point orientation problem.

👉 Therefore, the correct answer is: A. Two point problem
Key Points on Two Point Problem:
- Used when table is to be oriented from two inaccessible points
- Both points must be already plotted and visible
- Essential in hilly terrains or when access is restricted
- Part of the resection methods in plane table surveying
- Follows specific geometrical construction to fix current position
