What is the simple difference between real form and implied form?

Real form is truly 3D, implied form looks 3D in drawing

The governing concept is the distinction between actual volume and visual illusion. A real form exists physically in three dimensions: it has measurable depth, occupies space, and can normally be viewed from different sides, as with a sculpture or a cube. An implied form is created on a flat surface by visual clues such as contour, overlapping, perspective, light, and shadow; it appears solid but does not possess actual depth as an object. Option A correctly states this difference. Option C reverses the definitions because a touchable sculpture is a real form. Option D is false because a real form is not always flat, and option B is unrelated. Separating physical reality from drawn appearance is essential in form study.
