Why is perspective helpful in understanding form?

It creates an impression of depth and distance

The governing concept is linear and spatial perspective, which represents how objects appear to change with distance. Parallel edges may seem to converge toward vanishing points, nearer objects usually appear larger, and overlapping forms help establish position in space. These visual clues allow a flat drawing to suggest depth and help the viewer understand the orientation and volume of a form. Option A is correct because perspective creates an impression of distance, depth, and spatial placement. It does not directly increase colour brightness, change a surface into a rough texture, or produce sound. Those effects belong to colour, texture, or other sensory ideas. Thus perspective supports the illusion of three-dimensional form on a two-dimensional surface.
