The correct answer is the contour lines that are very close together.
Explanation:
A topographic map demonstrates the features of the surface, or topography of the Earth or of some kind of area. It shows natural features like lakes and rivers, it also shows elevation and certain features created by humans. The contour lines refer to the isolines or the lines on a map, which associates points with a similar elevation. Each of the contour line on a map demonstrates a distinct kind of elevation. The contour lines, which are close together demonstrates a steep slope on a topographic map.
