The correct answer is option C) method of resection.

Explanation:
The method of resection is a type of plane table surveying method that requires the help of another plane table for surveying the entire area completely. In this method, the surveyor sets up the plane table at a point where at least two points of the survey area are visible. The following are the steps involved in the method of resection:

1. Set up the first plane table: The first plane table is set up at a point where at least two points of the survey area are visible.

2. Set up the second plane table: The second plane table is set up at an unknown point in the survey area which needs to be surveyed.

3. Orient the first plane table: The surveyor orients the first plane table by using a known point from the survey area and aligning it with the corresponding point on the table.

4. Take backsights: The surveyor takes backsights from the first plane table to the known points in the survey area.

5. Take foresights: The surveyor takes foresights from the second plane table to the known points in the survey area.

6. Draw the survey area: The surveyor draws the survey area by plotting the intersections of the backsights and foresights.

7. Repeat the process: The above steps are repeated until the entire survey area is covered.

Advantages:
- The method of resection is useful in areas where it is difficult to set up the plane table at a point where all the points of the survey area are visible.
- This method is more accurate than the method of radiation.

Disadvantages:
- This method requires the help of another plane table and a surveyor.
- It is a time-consuming method.
