What insight does reading "letter to his father" give you about the metamorphosis?

a. that kafka felt turning into a bug was no big deal and gregor just had to get over it
b. that kafka had a negative view of father-son relationships, an element he included in his story
c. that kafka felt that gregor was lucky to be turned into a bug and should embrace the change
d. that kafka enjoyed writing about strong people because he was powerful as a child

The answer is B: That Kafka had a negative view of father-son relationships, an element he included in his story.

Through this text by Kafka, one can glimpse into the relationship that Kafka had with his father, and the feeling that father and son relationships aroused in the Czech writer: troubled, filled with anxiety and fear, but also plagued with an almost fratricidal or maniac urge to impose one´s own way of life above the father´s wishes, even if that should entail turning into a bug and becoming something so strange that the father figure could not even dare look at (like it happens in Metamorphosis).
