Which statement clarifies the relation between line and emotion in art?

Direction and quality of line can change mood

The governing concept is expressive line quality. A line is not merely a boundary or measuring device; its direction, pressure, speed, thickness, continuity, and curvature can suggest different emotional states. For example, smooth horizontal lines may feel calm, while sharp, broken, or strongly diagonal lines may suggest energy, conflict, urgency, or tension. Therefore, option A is correct because the direction and qualities of a line can influence the mood perceived in an artwork. Option B is false because line is a major expressive element. Option C is too narrow, since images can communicate emotion without written language. Option D describes only one possible technical use and ignores drawing, movement, rhythm, and expression. The emotional effect is not mechanical or identical in every culture, but artists deliberately use line qualities to guide interpretation.
