A. simplified shapes filled with bold, expressive color
In "Madame Matisse, the green line", Matisse portrays the female in a portrait pose, using a Fauvist style of painting, emphasizing bold, expressive color and a loose painterly quality. The specific "green line" down her face represents the changing light and contours of her nose. Although she is seated in a semi-traditional portrait pose, the answer is not D because portraiture is not necessarily a convention of Fauvism; this particular portrait also doesn't use line to frame the figure, therefore it is not C; and nor is the answer B as the focus of the image is a portrait and modern style of the era, not placed within a historical context.
