Answer:
The correct answer is: Contour Lines
Explanation:
Maps contain various elements that characterize them like Scale, Title, legend, Grids, etc. But other elements are only present in certain maps, like Isolines or points of interest that help classify types of maps. Topographic maps represent the earth's surface and elevation trough Isolines called Contour lines, these lines connect points of equal elevation value and are visible through all the map and only the Index contour lines are labeled to not make the map too dense.
