The answer is D. Nearing the end, Romeo hears that Juliet is dead and so he goes to buy poison from this guy, and after the "funeral", he sneaks into the tomb and cries and stares, not knowing that she had taken something to make it seem like she is dead. When she wakes up, he had already drank the poison and she, being devastated, grabs his knife and stabs herself in the chest.
