How can the use of empty space also become expression in art?

It can create a feeling of focus, peace, or loneliness

The governing concept is negative or empty space: an intentionally unoccupied area that participates in composition and meaning. It can separate objects, direct the eye toward a focal point, slow the visual rhythm, suggest distance, or make a subject appear isolated. A large quiet area around one small figure may communicate loneliness, while balanced open space can create calm and clarity. Empty space is therefore not automatically unfinished or wasted; its effect depends on placement, scale, contrast, and the artist’s purpose. Option A is correct because it identifies several possible expressive moods. Options B, C, and D treat all empty space as failure and ignore deliberate composition.
