Which option creates conflict between form and perspective?

The parallel edges of a box go toward unrelated vanishing directions without reason.

Perspective is a system for representing depth and the changing appearance of forms in space. In a box drawing, sets of parallel edges should follow a consistent construction system: in one-point perspective they move toward a common vanishing point, and in two-point perspective each relevant set moves toward its corresponding vanishing point. Option A creates the conflict because unrelated vanishing directions make the planes disagree about the box's orientation and depth. The object then appears twisted or impossible. Option B follows a coherent perspective system, option C correctly reflects the usual effect of distance, and option D supports believable structure. Before adding details, check edge direction, convergence, and the relation of near and far planes.
