On what basis is the correct position of the core shadow determined on a round object?

Answer and explanation

Correct answer: By the light source and surface curvature

The governing concept is the interaction between light direction and three-dimensional form. The core shadow appears on the part of a round surface that turns sufficiently away from the light, and its position shifts when either the light source or the surface curvature changes. Therefore option A is correct. Contour thickness, paper size, and pencil brand may affect presentation or marks, but they do not determine the physical location of the core shadow.
