Answer:
I don't think there is an error.
If there is, it's the 3rd option.
Perseus accidentally killed his grandfather, Acrisius in a discus throwing contest and fulfills the Oracle prophecy.

Step-by-step explanation:
B is more for a essay if you were studying something or someone.
C realy has nothing to do with it.
D that is one of the things but it wouldn't be a full explanation of the essay.
My choice would be the very last answer choice.
