What effect can be created by rotating similar shapes in different directions in a picture?

Visual movement and variety

When similar shapes are turned in different directions, the eye does not see them as completely still or repetitive. Their changing angles can guide the eye across the picture and create a feeling of movement. The variation also prevents the arrangement from looking dull or mechanically identical. The shapes remain related because they are similar, while their rotations add variety and visual energy.

Option A is correct because rotation changes the direction and visual rhythm of repeated shapes, producing movement and variety. The other choices describe effects that do not logically result from turning shapes: paper smell is unrelated, colour does not permanently disappear, and a picture does not produce sound merely because its shapes are rotated. Therefore, the strongest visual effect is a more dynamic composition.
