Which surface can be called rough texture?

Correct answer: Brick

The direct answer is option D: brick. Texture means how a surface feels or appears to feel, such as smooth, soft, uneven or rough. A brick normally has an uneven, grainy surface with small ridges and depressions, so it is a clear example of rough texture. Option A, glass, is generally smooth and even, so it represents the opposite type of texture. Option B, silk, is usually soft and smooth; it may have folds, but its surface is not normally called rough. Option C, polished metal, has been treated to become very smooth and reflective, so it is not the best rough example. Option D is correct because brick commonly has a coarse, uneven surface that can be felt by touch and shown in a drawing. Individual bricks can differ, but the school-level example is unambiguous. Memory cue: brick and stone suggest rough texture; glass and polished metal suggest smooth texture.
