Answer:
A) Krajiek is probably going to be a villain in the story.
Explanation:
The narrator, described Krajiek in the novel as follows:
"Peter was the Bohemian family's interpreter. He was like a mosquito that always hung around and wouldn't leave. He was a conman."
For the narrator to described Krajiek has a conman shows that, he's probably going to be the villain of the story.
Also, describing Krajiek as a mosquito that always hung around and wouldn't leave, means that, Krajiek is a character that not only cheat; by eating from where he did not work, but will ensure he finishes the whole food or resources before moving away.
In short, while he cheats and acts dubious, he is greedy to the level, that he does not know when to stop until, he finishes his prey.
Hence, the description point towards the fact that Krajiek is probably going to be the villain of the story.
