The methods used for locating the plane table stations are i) radiation ii) traversing iii) intersection iv) resection The correct answer is A. (i) and (ii) B. (iii) and (iv) C. (ii) and (iv) D. (i) and (iii)

The correct answer is (i) and (ii).

Radiation is a method of locating a plane table station by measuring the angles between the station and three or more known points. Traversing is a method of locating a plane table station by measuring the distances and angles between the station and two or more known points. Intersection is a method of locating a plane table station by measuring the angles between the station and two or more known points that are visible from the station. Resection is a method of locating a plane table station by measuring the angles between the station and three or more known points that are not visible from the station.

Radiation is the simplest and most common method of locating a plane table station. It is used when the plane table station is located close to the known points. Traversing is more accurate than radiation, but it is more time-consuming. It is used when the plane table station is located far from the known points. Intersection is the most accurate method of locating a plane table station, but it is the most time-consuming. It is used when the plane table station is located in a remote area. Resection is used when the plane table station is located in an area where there are no known points.
