B Correct answer
Explanation

Contour lines on a map connect points of equal elevation above a reference point like sea level. These lines are drawn at fixed vertical intervals and help visualize the three-dimensional shape of terrain on a two-dimensional map. Hachures show steepness, spot heights give individual elevations, and isomers are unrelated to maps.
