What is the main difference between geometric and organic shapes?

Geometric shapes are regular, organic shapes are often irregular

Geometric shapes are based on clear rules, measurable sides, angles, or curves. Examples include squares, rectangles, circles, and triangles. Organic shapes are usually inspired by living things and natural forms, such as leaves, clouds, stones, or the outline of a human body. They often have free, uneven, or irregular edges rather than exact mathematical measurements.

Option A gives the main difference accurately: geometric shapes are generally regular and organized, while organic shapes are often irregular and natural-looking. The word “often” is important because natural objects can sometimes contain geometric forms too. The other choices are incorrect because the two kinds do not always follow the same rules, organic shapes are not only squares, and geometric forms can certainly appear in nature and art.
