How can texture be expressed through line?

Correct answer: रेखाओं की दिशा और घनत्व से

The correct answer is A: texture can be expressed through the direction, spacing, thickness, length, and density of lines. Texture means how a surface appears or seems to feel, such as smooth, rough, hairy, woven, hard, or soft. Closely packed irregular strokes may suggest rough bark; short curved strokes may suggest hair; repeated parallel marks may suggest wood grain or cloth. A is correct because changing the arrangement and concentration of lines gives the viewer clues about a surface. B is wrong because changing paper alone does not show the texture of the pictured object. C is wrong because erasing the subject removes information instead of expressing its surface. D is wrong because writing a colour name does not visually describe whether a surface is rough or smooth. The same line method can suggest different textures when direction and density change. Memory cue: texture is “surface feeling”; show it with the behaviour of marks.
