A.) The speaker loves someone she is forbidden to see.
Explanation:
A is the only option that makes sense. "Romeo, take me somewhere we can be alone. I'll be waiting; all that's left to do is run."
"Somewhere we can be alone" and "all thats left to do is run" don't suggest that the speaker has been waiting, neither do they suggest that the speaker loves someone who doesn't care about her.
They do suggest that the speaker loves someone she is forbidden to see.
