Answer: B. He and Claudius are relatives but not similar to each other.
Explanation: In this reference, Shakespeare plays with the similar-looking words kin and kind to have Hamlet express in a witty way that although Claudius is now "a little more" than his relative (he is now his uncle and stepfather), he is "less than kind"; the word kind means at least two things: that Claudius is still not his direct ancestor and that Claudius is not a kind (considerate) person. Kind also meant gender, so it could imply that Hamlet thought his uncle was less of a man than his father. In any case, Hamlet implies that he and Claudius are not the same kind of person.
