How can line suggest heaviness or lightness of an object?

Thick, dark lines can suggest heaviness, while thin, light lines can suggest lightness

The governing concept is line weight, meaning the visual force created by a line’s thickness, darkness, pressure, and prominence. A thick, dark, strongly pressed line usually makes an edge or object feel solid, stable, powerful, or heavy. A thin, pale, delicate line may suggest fragility, distance, softness, or lightness. Therefore, option A is correct because it accurately connects visual line weight with the impression of an object’s heaviness or lightness. Option B is false because line qualities produce different effects. Option C denies the central principle, and option D confuses visual weight in art with the physical weight of the paper. The effect is an artistic suggestion, not a measurement of actual mass.
