In which condition will an organic shape be most suitable?

While showing a natural cloud or leaf

Organic shapes are inspired by living things and natural surroundings. They are often irregular, flowing, uneven, or curved rather than perfectly measured. Examples include the shapes of clouds, leaves, stones, flowers, waves, and tree branches. Using an organic shape is useful when an artist wants a picture to feel natural, flexible, or lifelike. Organic does not mean that every natural object has no pattern; it means the shape is not mainly based on exact geometric measurement.

Choice B is correct because a natural cloud or leaf is best represented with a freely formed, irregular shape. A measured traffic symbol, an exact square, and a mathematical diagram generally need geometric shapes with controlled sides, angles, or proportions. Those choices therefore do not demonstrate the main use of organic shape as clearly as a cloud or leaf does.
