In the passage, you can see one thing slowly leads to another: Oedipus accidentally kills his father, and because of that Jocasta kills herself, leaving Oedipus to resign from the throne. If Oedipus had not killed his father, then Jocasta wouldn't have killed herself, and he wouldn't have left the throne.
It's not B. It doesn't have quotation marks. Not C because the first word in the quotations needs to be capitalized. Not D because the quotation need to surround the statement. So your answer is A :) Hope this helped :)
I think C stresses the the point of the storm missing a certain area better most specifically. Mostly because it gives the direction that it headed after skipping a certain sector.
