The setting suggests that the author identifies with the unsung heroes of the world (B).
First of all, the story is dystopian, which means that the author is denouncing, and not praising, a certain system. Dystopia is often used as a caricature of phenomena the author views as threats (artifical intelligence, for example).
Second, the protagonist contrasts with this system, which indicates that she is probably depicted as an admirable character and that the writer is on her side.
From this, you can infer that this story is a caricature of the way our world sometimes fails to recognize the exploits of some people, and maybe even praises these people for being humble about it.
