Help with answer D

Is D the correct answer because references to expressions of emotions and psychological symbolism ("his use of muted colors... to suggest moods of melancholy and despair... colors also served as symbols of the psychological effects of debilitating social processes") does not specifically point to the human figures in his painting, but rather, to the "colors" in his painting generally? his use of muted colors... to suggest moods of melancholy or despair... these colors also served as symbols of the psychological effects of... debilitating social processes.
