What limitation occurs if wood texture abruptly stops at the light-shadow boundary?

Correct answer: Instead of showing lighting on texture it will appear like a separate layer

The governing concept is continuity of surface texture under changing light. Wood grain does not physically disappear at the light-shadow boundary; it becomes darker, softer, or less distinct as illumination decreases. Stopping it sharply makes the texture look pasted on as a separate layer instead of belonging to the wooden form. Thus option B is correct. Symmetry, object stability, and cast-shadow length are unrelated effects.
