Answer:
Option (A)
Explanation:
Topographic maps are defined as those maps that highlight the topography of an area, the type of relief and heights of the hills and valleys are usually shown in terms of contour lines. They can be large scale maps or small scale maps.
The earth's surface is shown on the map in terms of elevation. These elevations are known as contour lines.
Contour lines are defined as the lines of equal elevation and they never intersect each other. Each contour line is highlighted with a number that represents the elevation at that point from the mean sea level. This elevation contours are a key characteristic that helps in understanding the topography of the area provided in a map.
Thus, the correct answer is option (A).
