Which option is an example of line quality?

Correct answer: Thick and thin

Direct answer: B, thick and thin, is an example of line quality. Line quality means the character or visual manner of a line—how heavy, light, thick, thin, dark, pale, smooth, rough, continuous, or broken it appears. A line can communicate different feelings and details through these changes. A thick line may look strong or heavy, while a thin line may look delicate or light. Option A, red and blue, names colours, not the character of a line. Option C, black and white, describes colours or values; they can be used in a line, but the pair itself is not line quality. Option D, near and far, describes distance or space. Therefore, B is correct because thickness is a direct quality of a drawn line. Memory cue: line quality asks “What kind of line is it?”
