Answer
Brief Explanations:
To determine the answer, we analyze each option:
- Option a (intensity) relates to the brightness of light, not 3D perception.
- Option b (hue) is about the color type (e.g., red, blue), not 3D.
- Option c (color) refers to the general property of light's color, not 3D perception.
- Option d (shading) creates the illusion of depth and 3D by showing light and dark areas on objects, helping observers perceive three - dimensions.
