What limitation occurs if all dark areas of a glossy black object are uniformly black?

Correct answer: Differences in reflections and surface turning will weaken

The governing concept is value variation on reflective surfaces. Glossy black objects still contain subtle differences between reflected lights, reflected darks, highlights, and turning planes. If every dark area is filled with the same black, those distinctions disappear, so the viewer cannot clearly read the surface curvature or separate reflection shapes. Therefore option B is correct; uniform black does not improve symmetry, cast-shadow accuracy, or scale.
