If form structure is correct but value direction is wrong what conclusion follows?

Correct answer: The light-and-shadow logic of the form is weak

Correct answer: A — the light-and-shadow logic of the form is weak. Form means an object understood as having three-dimensional volume. If its structure is correct, the basic shape, proportion, and construction may already be sound. Value direction concerns where the light, middle tones, and shadows are placed in relation to the light source. If these values run in the wrong direction, the object may look flattened, twisted, or inconsistently lit even though its construction is correct. A is correct because the error lies in the three-dimensional lighting logic. B is wrong because the question explicitly says that the structure is correct. C is wrong because symbolic colour meaning is not the issue being described. D is wrong because texture details are separate from the direction of light and shadow. Before applying values, decide where the light comes from and keep all planes consistent with that source. Memory cue: correct structure gives the object its build; correct values give it believable volume.
