In which option is it most appropriate to call art a visual language?

Because art gives messages through line, colour, shape, and form

The governing concept is visual language: a system in which elements such as line, colour, shape, form, space, and texture function as signs that communicate ideas or feelings. A viewer can understand emphasis, mood, direction, identity, or relationships even when an artwork contains no written or spoken sentence. Option A is correct because it identifies the visual elements that carry meaning and shows why art can communicate without ordinary speech. Option B is contradictory because spoken words belong to an oral language, not the definition of visual language. Option C wrongly rejects signs, and option D reduces expressive arrangement to numerical calculation. Interpretation still depends on context and visual organization.
