Which feeling can a zigzag line make more effective in a poster?

Tension or sudden energy

The governing concept is the expressive effect of angular, repeated changes in line direction. A zigzag line contains sharp turns and an irregular back-and-forth path. These sudden changes make the eye move quickly and create visual tension, alertness, agitation, or energetic impact. In a poster, that quality can attract attention and make a warning, urgent message, conflict, or exciting action feel stronger, so option B is correct. Complete peace and slow stability are more commonly associated with quiet horizontal or gently flowing lines. Silence and emptiness depend more on sparse composition and open space, not automatically on zigzag marks. The exact feeling still depends on colour, scale, placement, and context, but tension or sudden energy is the most appropriate answer.
