How can the weight of an object be suggested through line?

Correct answer: By using thick and dark lines at the lower part

Correct answer: A, using thick and dark lines at the lower part. In a drawing, visual weight is the sense that one area feels heavier, stronger, or more firmly supported than another. Thick, dark marks attract attention and create greater visual density. Placing them near the lower part can suggest that an object is grounded, pressing downward, or carrying weight. A is correct because line thickness and darkness communicate emphasis and support. B is incorrect because erasing an upper section removes information rather than showing weight. C is incorrect because writing a colour name does not create a visual mark or indicate physical heaviness. D is incorrect because equally light lines everywhere create little emphasis or difference in weight. The effect also depends on context, shape, position, and surrounding empty space; lines alone do not literally measure mass. Use the marks deliberately and avoid making every part equally dark. Memory cue: thicker, darker, concentrated lines feel heavier; thin, light, open lines feel lighter.
