In which condition can hierarchy be intentionally kept flat in shape-based design?

Giving all shapes equal importance in a decorative pattern

The governing concept is visual hierarchy: the deliberate ordering of elements from most to least prominent. A flat hierarchy gives several elements nearly equal emphasis rather than directing the eye toward one dominant focal point. This can be appropriate when the purpose is repetition, rhythm, pattern, or an even decorative surface. Option A is correct because a decorative pattern may intentionally treat repeated shapes as equal units. Options B, C, and D require communication priorities: a poster needs a clear focal message, a narrative scene needs the main character to stand out, and a safety sign must make its symbol immediately noticeable. Those purposes call for stronger hierarchy, not a flat one.
