A flower petal can be understood as what kind of shape?

Organic shape

An organic shape is a natural-looking form that is usually irregular, soft, or flowing rather than made from exact geometric rules. Flower petals vary in curve, size, and outline, and they are found in nature, so they are good examples of organic shapes. A petal may sometimes be simplified into an oval or another geometric form in a drawing, but its natural character is organic. The question asks for the most suitable art classification.

Option D is correct because a flower petal is a natural form with a curved, non-mechanical outline. Options A, B, and C describe exact geometric shapes with straight, measured sides or only straight edges. Those descriptions do not normally match the flexible form of a petal. Observing whether a shape comes from nature and whether its outline is irregular helps identify it as organic, so D follows clearly.
