Contour interval means a vertical difference between two consecutive contour lines.
But here, the horizontal distance between 2 contour lines.
Now, here flat terrain means Horizontal Distance between two contour will very high but vertical distance will be very low. Then it will be called as flat terrain.

Very flat terrains have a minimum little elevation difference over a large area.
Hence spacing between two contour lines is also very large. Therefore giving spot levels at close intervals will give a better representation of very flat terrains.

A should be the correct answer because in hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes.

Agri @Saurav.
Option B is correct because in flat terrain in the contour interval will be very less for very large horizontal distances that can be possible to depict the general topographical features.

D is correct because very flat terrains have minimal elevation over large area, hence spacing between contour lines are large, therefore giving spot will at close interval give good representation.

In flat terrain the elevation difference is slight. So when we draw contours of this region, the salient features of the ground could not be represented.

Option B, For a very flat terrain, the difference of elevation is not large hence contours can be drawn at smaller interval for better detailing.

Large contour interval is for undulated ground.
For levelled or flat terrain small (close) contour interval is used.

I think option a is correct because in a flat ground change of slope is less. So large interval is used.

Option D is the correct answer.
Because it's given salient features (most important things).
