Answer: B.
Explanation: Option D is discarded because the sentence clearly needs to have its punctuation fixed; option C is wrong because the independent clause "it was unbelievable..." cannot be introduced with a comma, and while options A and B seem viable, the abrupt interruption of the normal flow of the sentence demands the use of dashes.
If the sentence has changed you would have to put a period.
The order in which the characters die in Act V, scene 3, would be Paris, Romeo, then Juliet, so option 3.
