Hey! Your answer would be B, tourism.
<span>A topographic map is the best tool for this purpose.
In addition to being used for directional navigation, topographic maps also give the user a means by which to understand elevation in the area they climbing. These maps include topographic lines where each line represents an elevation and the distance between lines can be used to determine the terrain profile.</span>
The correct answer is - c. a steeper slope.
When the contour lines on a topographic map are very close it means that there is a steeper slope. The contour lines are a very good, easy, and efficient way of depicting the relief; the closer the contour lines are, the steeper the place, the further away the contour lines are, the flatter the place. On certain places where the steepness is to big (usually a vertical fall) instead of using the standard contour lines, there are special ones that are like small stripes directed into the direction of fall, which is also very well represented and very helpful.
