The correct answer is A. tacheomefry.
Tacheometry is a surveying method that uses a tacheometer, a surveying instrument that measures angles and distances. Tacheometry is a rapid and accurate method of surveying, and it requires less office work than other methods of surveying.
Trigonometrical levelling is a surveying method that uses trigonometry to measure the difference in elevation between two points. Trigonometric levelling is a precise method of surveying, but it requires more office work than tacheometry.
Plane table surveying is a surveying method that uses a plane table, a drawing board that is mounted on a tripod, and a alidade, a sighting device. Plane table surveying is a relatively accurate method of surveying, but it requires more office work than tacheometry.
Theodolite surveying is a surveying method that uses a theodolite, an instrument that measures angles. Theodolite surveying is a precise method of surveying, but it requires more office work than tacheometry.
In conclusion, the type of surveying which requires least office work is A. tacheomefry.
