Which option creates contrast between visual stability and restlessness through line?

Shaky diagonal lines above a calm horizontal base

Different line directions and qualities can communicate different visual moods. Horizontal lines are commonly associated with rest, steadiness, and a stable base, while shaky diagonals suggest movement, imbalance, tension, or restlessness. Option A is correct because it places these contrasting qualities together: the calm horizontal foundation provides stability and the irregular diagonals introduce disturbance. Options B and C may establish consistency or rhythm, but they do not clearly set stable and restless line moods against each other. Option D removes the line element and therefore cannot create this particular contrast through line. The effect is not a fixed rule, but the deliberate difference in direction and character makes A the strongest answer.
