Which is the correct example of real form and implied form?

Sculpture is real form, while a 3D illusion made by shading in a drawing is implied form

The governing distinction is between actual three-dimensional existence and the visual suggestion of three-dimensionality. A sculpture occupies physical space: it has measurable height, width, and depth and can be viewed or touched from different sides. That is real form. A drawing or painting remains physically flat, but carefully controlled contour, perspective, light, shadow, and tonal value can make the viewer perceive depth; this is implied form. Option A correctly pairs these examples. Option B is too narrow because neither category is defined as merely a line. Option C reverses the meaning, since touchable stone is an example of real form. Option D also reverses the relationship: a paper drawing can suggest form, but it is not automatically real form.
