b. The painting has an overall decorative-pattern effect and a flattened sense of space. 
Explanation:
Fauvism has as its common axis the exploration of the wide possibilities posed by the use of color. The freedom with which they use pure tones, never mixed, manipulating them arbitrarily, far from concerns with verisimilitude, gives rise to flat surfaces, without light-dark illusionists. The sharp brushes build spaces that are, first of all, smooth areas, illuminated by reds, blues, and oranges. Fauvism was an experimental stage in European art, and Matisse was its major representative. That's why his painting has this pattern of colors and the way he arranges the objects in the canvas. Everything was made to expand the boundaries of the art, and the understanding of it.
