How do shape and texture together strengthen object quality?

Irregular stone shape and rough texture together show stoniness

Shape tells us about an object’s outline and overall structure, while texture suggests how its surface might feel or appear. When both clues agree, the object becomes easier to recognise and its material quality becomes more convincing. An irregular outline combined with a rough visual surface suggests a natural stone because both features support the same idea. Artists can use this relationship to make objects look hard, soft, smooth, rough, natural, manufactured, or worn. Neither element has to work alone.

Choice A is correct because an irregular stone-like shape and rough texture together communicate the quality of stone. A shape does not automatically erase texture, and texture is closely related to how an object is understood. A smooth circle could represent many things, but by itself it does not always show stone. The strongest result comes when the outline and surface treatment support one another.
