Answer: C. It looks at life, even unpleasant aspects, truthfully.
Explanation: Realism, as a movement in literature and art, is a way of presenting the material "truthfully," rather than allowing for fantasy and the previous romantic era tendencies. The work can still be creative. This just means that it is based more on "real" life as we (humankind) factually or experientially know it to be. There is still a wide margin for differences in what is considered or interpreted to be a truth or "true to life" within the style of realism, given that people are all different from one another and react to life with a broad range of emotions, viewpoints and backgrounds that they bring to the story.
