For what purpose is a contour line used?
Answer and explanation
Correct answer: To show the outer and surface form of an object
A contour line follows the edge or changing surface of an object and helps communicate its shape and form. An outer contour can describe the silhouette, while lines that follow surface changes can suggest turning, roundness, or volume. Therefore, option A is the best answer because it includes both the external boundary and the surface form. A contour is not used merely for writing a title, erasing colour, or attaching a frame. The distinction is useful: an outline generally emphasizes the outside edge, whereas contour drawing may study how the visible edge and surface direction describe the object’s three-dimensional character.
