The answer is B: Gregor´s transformation into a bug.
It is funny that, in this story by Franz Kafka, Gregor, the main character, finds himself turned into a bug for no apparent reason. His reasoning is not concerned with the reasons why that could have happened, but rather, with how it will affect his work, his family, and how uncomfortable it will be for them. Amongst many other themes explored in the story, certainly the main character´s and the author´s inadequacy is clearly in display.
