If an art form depends on object, sound, and viewer movement, how is it better understood?

Multimedia experiential art

The governing concept is that some contemporary or mixed art forms combine several media and make the viewer’s experience part of the work. An object can provide a visible or physical element, sound can create an auditory layer, and the viewer’s movement can make the experience change with position, distance, or participation. When these components operate together, the artwork is best understood as multimedia and experiential. Option B is correct because it includes both the combination of media and the changing experience of the audience. A flat painting mainly depends on visual marks in two dimensions, a fixed sculpture mainly depends on a stationary three-dimensional object, and literary art mainly uses language. Those descriptions do not account for the complete combination of object, sound, and viewer movement.
