The answer is B: Through Gregor's transformation into a hideous bug.
In this story by Kafka, we find the main character, Gregor Samsa, transformed into a bug for no apparent reason. As the story develops, we confront the main character´s struggles to conform and adapt to his new bodily form, evidently, without success. The most straightforward interpretation of the story is that the author evidenced his own feelings of inadequacy in life and in love through his fictional character, Gregor.
