If line is absent but figure is still clear what advanced control is the artist using?

Correct answer: Control of value, colour and edge contrast

Correct answer: A — control of value, colour, and edge contrast. A figure does not always need a drawn outline. The eye can recognise it when its lightness or darkness differs from the surrounding area, when its colour contrasts with the background, or when the boundary between two areas is deliberately made sharp or soft. These relationships allow the artist to suggest a clear shape without using a separate line. A is correct because it describes the visual controls that make the figure readable. B is wrong because paper thickness may influence the handling of a medium, but it does not normally create the visible boundary of the figure. C is wrong because the frame is outside the principal image and cannot explain the internal figure. D is wrong because a title has no direct role in making the depicted figure visually clear. Remember that an edge may be implied by contrast rather than drawn as an outline.
