In which art type can real space, viewer movement, and arrangement of objects matter together?

Installation art

The governing concept is installation art, in which an artist arranges objects, materials, images, sounds, or structures within a particular environment. The space is not merely a background; it becomes part of the artwork and influences how the work is understood. The viewer may walk around, enter, or move through the arrangement, so bodily position and movement can change the experience. Option C is correct because installation art combines spatial organisation, objects, and active viewing in a real place. Calligraphy mainly emphasises written and visual form, radio music is primarily auditory, and a written story is mainly experienced through language and imagination rather than through movement in an arranged physical space. These alternatives do not include all three stated features together.
