The answer is your last option: <u>Although fate plays a role in the tragic end of Romeo and Juliet, they are the victims of their own choices.</u>
Explanation:
The first option isn't possible as it talks about Shakespeare's work, and not about Romeo and Juliet's best statements for an analysis. The second option is rather general and somehow false, as it isn't foreshadow if you haven't read the story. Option three is not complete, because indeed, fate is an important role, probably not the central theme, but it is missing what option D offers, --they are victims of their own choices-, this is why is your last option.
We know the speaker has had a hard life because "old Time's tuck his toll." By this, he means that time has taken its toll -- the years have been difficult.
