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
