How does line clarify the relation between form and space?

It explains object position through boundary, overlap, and direction

The governing concept is that line is both a boundary-making and spatial-organising element of art. A contour line separates an object from the surrounding negative space, while overlapping lines show which form is nearer and which is behind. Directional lines can also guide the eye and suggest orientation, movement, or recession into space. Therefore, option A is correct because boundary, overlap, and direction together help the viewer understand an object's position and relationship with nearby forms. Option B concerns paper material, not spatial representation. Option C is too absolute because lines can suggest volume and depth rather than always flattening a form. Option D is false because line is one of the main tools for organising space.
