What is the correct reason for using different values on the three planes of a cube?

Answer and explanation

Correct answer: Each plane faces the light differently

The governing concept is light-and-shade modeling. The three planes of a cube face different directions, so a single light source illuminates them by different amounts. The plane facing the light is usually lighter, the turned plane is darker, and another plane may show a middle value. Thus option B is correct. Different materials, sizes, or pencils are not the necessary reason for the value difference.
