If form shadow is correct but cast shadow on ground is absent which illusion weakens?

Answer and explanation

Correct answer: Object resting on surface

The correct answer is A: the illusion that the object is resting on a surface becomes weak. A form shadow is the darker part on the object itself, away from the light, and it helps describe roundness or volume. A cast shadow is different: it is thrown by the object onto the floor, wall, or another surface. It shows contact with that surface and gives a clue about the direction of light. If the cast shadow is missing, the object may appear to float even when its three-dimensional shading is accurate. Option B concerns the meaning of colour, not physical contact. Option C concerns decoration and does not anchor an object. Option D concerns symmetry, not light or weight. Memory cue: form shadow describes the object; cast shadow places the object.
