Cube sphere and cylinder are examples of which element?

Form

A cube, sphere and cylinder are solid objects that have three dimensions: length, breadth and height. They occupy space and can be viewed from different sides. In visual art, an object with three-dimensional presence is called a form. A cube has flat surfaces, a sphere has a rounded continuous surface and a cylinder has circular ends with a curved side, but all three are forms because they show volume and depth.

Option C is therefore correct. Line is a mark with length, shape usually refers to a flat two-dimensional outline, and value describes how light or dark something appears. A drawing may use lines, shapes and values to represent these solids, but the solids themselves are examples of form. The important test is whether the object has depth and occupies space, not merely whether it has an outline.
