Contour bunding is a method of soil conservation used in
- (a) Desert margins, liable to strong wind action
- (b) Low flat plains, close to stream courses, liable to flooding
- (c) Scrublands, liable to spread of weed growth
- (d) None of the above
Show the answer and explanation
Answer: (d) None of the above
Contour bunds are built along contours on sloping or undulating land to slow run-off — none of the listed settings.
Why the others are wrong
(a) Deserts need windbreaks and shelterbelts, not bunds.
(b) Flat floodplains don’t need contour bunds.
(c) Weeds are not controlled by bunds.
The trap
Each option names a real problem with a different fix.
🔒 Contour bunding / terracing = slopes · windbreaks = deserts · afforestation = ravines.
