Answer: B. It just states what happened in the text, rather than finding implicit meaning.
An interpretive argument is meant to help you dissect a piece of information that is not clearly stated or that has a hidden, second meaning. In this case, the explanation is simply restating what the rhyme says, not "interpreting."
A better exercise would be to argue, for example, that Humpty Dumpty died from the fall. This would mean that "to break" is another way of saying "to die," except that the rhyme does not state it as such. In this case, you would have found a hidden meaning behind the literal phrase, and it would be a case of interpretation.
