What problem occurs if the cast shadow shape remains unchanged even when the light direction changes?

Answer and explanation

Correct answer: The observed shadow will be unconvincing

The governing concept is the relationship between light direction and cast-shadow direction. When the light moves, the shadow changes its direction, length, and often its shape because it is formed by the object blocking that light. Keeping the old shadow unchanged creates a visual contradiction, so the drawing becomes unconvincing. It does not enlarge the object, automatically darken its colour, or primarily reduce symmetry; therefore option D is correct.
