Which cues together help show a form placed in space?

Perspective, cast shadow, and scale

A form appears convincingly placed in space when several visual cues agree. Perspective helps show direction and distance; relative scale suggests that distant objects appear smaller than comparable nearby objects; and a cast shadow anchors the form to a surface, indicating contact, light direction, and position. Therefore, option A is correct. The other choices refer to smell, sound, dates, titles, or framing, which do not establish spatial placement. An outline can identify the boundary of a form, but an outline alone does not explain depth or contact with the ground. Artists strengthen spatial realism by combining these cues with overlap, atmospheric perspective, value changes, and careful placement rather than relying on one device in isolation.
