Line is used to define a shape, the path between two points, and to create movement or lead the viewer's eye.

• A. The line defines shapes and guides the eye
• B. It is only used to outline objects
• C. It can be used to create shading
• D. It is always straight

Answer: (A)

Lines in art describe edges, connect points, and guide the viewer through a composition. The statement that line defines shapes and guides the eye captures how lines form the boundaries of shapes and also direct attention: the direction, thickness, and rhythm of a line can lead your gaze from one area to another, creating a sense of movement. A line isn’t limited to just outlining objects; it can also imply shading through hatch marks, and it isn’t restricted to being straight—curved or diagonal lines can convey action and propel the viewer’s eye along a path. So, the best description emphasizes both how a line defines form and how it actively directs visual flow in the artwork.
