Showing wood grains in a drawing is the use of what?

Correct answer: Visual texture

Correct answer: C, visual texture. Wood grain is a pattern that tells the viewer about the surface and material of wood. When an artist draws those lines, curves, and variations on paper, the paper does not become wood physically; instead, the marks create a visual impression of wood. That makes this an example of visual texture. Option A is wrong because colour temperature describes the warm or cool feeling of colours, not the grain pattern of a surface. Option B is wrong because form concerns a three-dimensional appearance or structure, while the question focuses on surface markings. Option C is correct because wood grain communicates surface quality through sight. Option D is wrong because positive space is the occupied area of a subject or object, not the pattern on its surface. The grain may help identify the material, but its main role in this question is textural representation. Memory cue: if marks tell you how a surface seems to feel or what material it is, think texture.
