Why would dense zigzag lines be unsuitable in a calm temple scene?

Correct answer: They will show restlessness and tension instead of calmness

Direct answer: A is correct. Line character affects the mood of an image. Zigzag lines contain repeated sharp changes of direction, so they often suggest nervous movement, conflict, danger, or strong energy. If many such lines are placed in a scene intended to feel calm, they fight against the peaceful mood of the temple and may make the scene feel restless or tense. A is correct because it connects the visual quality of the line with the intended atmosphere. B is wrong: line direction alone does not physically increase a temple’s height. C is wrong: zigzags do not automatically establish correct perspective; perspective depends on an organized spatial system. D is wrong: a line can sometimes indicate light direction, but dense zigzags do not inherently identify a light source. Memory cue: smooth and quiet marks support calm; sharp repeated changes suggest agitation.
