Control of the viewer's eye through line is connected with which principle?

Correct answer: Directional movement, emphasis, and visual path

Direct answer: D, directional movement, emphasis, and visual path. Lines can guide the viewer’s eye through an artwork. A diagonal line may lead the eye upward or across the composition; a curved line may create a flowing route; and converging lines may point toward a particular area. When these lines bring attention to the main subject, they create emphasis and establish a visual path. Option A is wrong because symmetry and balance mainly concern stability and distribution, although they can influence viewing. Option B is wrong because proportion and scale concern relative size and measurement, not primarily the route of the eye. Option C is wrong because texture concerns surface quality rather than direct eye guidance. Option D is correct because it names the connected ideas of movement, emphasis, and visual direction. Memory cue: ask, “Where does this line make my eye travel?”
