Answer 1

The correct option is D isolines

A line on a map joining places of equal values is called an isoline.

Isolines, also referred to as contour lines, can be used to represent elevation on a map by connecting points of equal elevation, for instance. As with all isolines, when contour lines lie close together, they represent a steep slope; lines far apart represent a gradual slope.
