In which condition will observing negative shape help find an error?

When the outer boundary or proportion of an object seems wrong

Negative shape is the empty area around, between, or inside objects. It has its own shape and can be observed like any other visual form. When an artist checks this empty space, it becomes easier to notice whether an object’s outer boundary, size, angle, or proportion is inaccurate. This method is especially useful because the eye may overlook mistakes when it concentrates only on the object itself.

Option A is correct because an incorrect boundary or proportion changes the shape of the surrounding negative space. Looking at that space can reveal that an object is too wide, too narrow, tilted wrongly, or placed incorrectly. Options B and C concern colour names and materials, not visual proportion. Option D is unrelated: negative space is examined to improve the drawing, not to hide its shape.
