Which option correctly relates form to a natural object?

Understanding a tree trunk as cylinder-like and fruit as sphere-like

The governing concept is structural analysis: complex natural objects can be understood by comparing their volume with simple three-dimensional forms. A tree trunk often has a cylindrical or tapered cylindrical structure, while many fruits have a rounded, spherical or oval volume. This comparison helps the artist construct proportion, perspective, light, and shadow more accurately, so option A is correct. Option B reduces a solid object to a flat mark and ignores depth. Option C imposes an unsuitable geometric model on every fruit, even though fruits vary greatly. Option D removes the trunk’s length and volume altogether. Simplification is useful only when it preserves the important spatial character of the object.
