How can both tension and calmness be shown through line in a picture?

Correct answer: Through contrast of zigzag and horizontal lines

Correct answer: A, by contrasting zigzag and horizontal lines. Different kinds of lines communicate different visual feelings. Sharp zigzag or angular lines often suggest agitation, conflict, sudden movement, or tension. Long, level horizontal lines usually feel settled, quiet, and stable. When these types are placed thoughtfully in one picture, the composition can express both an active or tense area and a calm area. A is correct because the contrast itself creates a difference in mood. B is wrong because removing all lines removes this particular means of expression. C is wrong because one point alone cannot clearly establish both opposing moods through line. D is wrong because making every line identical reduces contrast and emotional variety. The effect depends on context, placement, spacing, and scale; no line has only one permanent meaning. Memory cue: jagged suggests disturbance, level suggests rest.
