Answer 1

The correct option is A Benchmark

Benchmark is a surveyor’s mark, cut on a rock, stone, wall or a building showing the height of that mark above sea level. Contours are lines shown in brown, joining places of equal height above the sea level. Heights of inaccessible areas are shown by contours drawn in broken lines called form lines.
