Which of the following is not most suitable in chain survey?

A. irregular slopes
B. rocky environments
C. embarkment areas
D. plain topography

Correct Answer:

Option D – plain topography

Explanation

The answer is D, all other options are wrong because they are not too suitable for chain survey to their landforms(topography)
Plain topography is the most suitable in chain survey because in chain survey, the only instruments required are a pair of compass and a scale rule. On the plain topography, there is no bend or contour which makes the setting of compass easy and chain throwing is not stressful
