What effect can uncontrolled use of many zigzag lines create in a poster?

Visual disorder and an unclear message

Zigzag lines are energetic because their repeated changes of direction create sharp movement and visual excitement. Used selectively, they can attract attention, suggest danger, communicate urgency, or add liveliness to a poster. However, if many zigzags are placed without control, spacing, hierarchy, or a clear purpose, they compete with the title, images, and other information. The viewer’s eye may move in too many directions, making the composition visually noisy and the intended message difficult to read. Option A correctly describes this risk. Option B may occur only when line energy is carefully balanced, not when it is uncontrolled. Options C and D do not follow from using zigzag lines. The governing concept is that expressive marks must be organised according to communication needs; visual energy supports a poster only when clarity and hierarchy are preserved.
