What can be the biggest problem if shape hierarchy is disturbed in a composition?

Visual confusion can arise between main and secondary parts

Shape hierarchy is the visual order that tells the viewer which parts of a composition are most important and which parts support them. Artists can create this order through differences in size, position, contrast, detail, or visual strength. If that order is disturbed, a secondary shape may attract as much attention as the main subject, or the viewer may not know where to look first. The composition can then feel confusing even if its individual shapes are well drawn.

Option A is correct because a disturbed hierarchy can create visual confusion between main and secondary parts. The other choices describe effects that do not follow from shape hierarchy: shapes do not automatically become balanced, paper thickness does not change, and colour smell is unrelated. Thus, the key problem is loss of clear importance and focus.
