Which statement about directional light rays is true?

Explanation:
Directional light in 3D rendering is modeled as coming from infinitely far away, so its rays are parallel. This mirrors how sunlight behaves: all rays travel in roughly the same direction, producing consistent illumination and parallel shadows across the scene. Divergent rays would come from a nearby point source and spread outward, which isn’t how directional light behaves. Radial or circular rays aren’t standard descriptors for directional lighting and don’t describe its parallel propagation.
