How can foreground and background be separated through shapes?

By keeping front shapes larger and clearer, and back shapes smaller and lighter

Foreground and background are depth layers within a picture. A shape placed in the foreground is usually made larger, more detailed, sharper, or stronger in contrast, while a background shape may be smaller, less detailed, lighter, or less distinct. These differences in scale and clarity create visual depth and help the viewer recognise spatial order, so option A is correct. Option B reverses the usual depth cue by making distant forms unnecessarily heavy. Option C removes useful differences, making the layers harder to separate. Option D does not create a foreground-background relationship at all; it simply removes an important part of the picture. Artists may intentionally break these conventions, but for a clear conventional depiction, size and clarity provide reliable separation.
