Why does changing the edge quality of a shape change viewer experience?

Soft and hard edges create different visual character

The edge of a shape affects how clearly, softly, strongly, or gently it appears. A hard edge is sharp and definite, so it can make a shape look clear, firm, tense, or bold. A soft edge is less sharply separated from its surroundings and may suggest gentleness, distance, atmosphere, or calmness. These effects influence the viewer’s emotional and visual response even when the basic shape remains unchanged.

Option A is correct because soft and hard edges create different visual characters and can suggest different moods. An edge is not merely a cutting part of paper; it helps define what the viewer sees. Saying that every edge gives the same mood ignores this difference. Artists may use hard edges to focus attention and soft edges to reduce emphasis or create a gentle transition between areas.
