Which line can suggest the flow of wind?

Correct answer: Light flowing curved lines

Correct answer: A, light flowing curved lines. Wind cannot normally be seen directly, so an artist represents it through signs such as the bending of grass, movement of leaves, flowing cloth, or sweeping lines. A light curved line gives a sense of direction and continuous movement, allowing the viewer to imagine air passing through the scene. Option A is therefore appropriate. B contains hard, static forms that suggest rigidity and stillness rather than moving air. C is a boundary around a shape; it encloses an object but does not show a current. D is only a point and has no length or direction, so it cannot communicate wind flow by itself. Memory cue: invisible movement is often suggested with light, directional, flowing lines.
