In a linear pattern, illusion of depth can be created not only by size but also by what?

Correct answer: Line density, overlap, and direction

Lines can suggest depth because viewers interpret their spacing, direction, overlap, and concentration as spatial clues. Lines that become smaller, closer together, or more crowded may suggest distance, while overlapping lines can show which form is in front. Directional lines can guide the eye toward or away from a region and can create a sense of recession, movement, or perspective. These effects work even in a simple linear pattern.

Option A is correct because line density, overlap, and direction can all help create an illusion of depth. The subject’s name does not create spatial depth by itself, and paper colour alone is not enough. Frame thickness is a physical border rather than a principal depth cue within the drawing. A strong composition may combine line size with these other visual signals, so depth should not be judged from size alone.
