Answer:
B. there is no proximate cause between the breach of duty and the injury.
Step-by-step explanation:
In law, proximate cause is a situation when the action of the defendant is directly causing the negative situation that happened to the other party.
From the case above, Homer could try to argue to the judge/juries that the reason why Patty tripped is because of her cat rather than his crash.
The judge and juries can either agree or disagree with homer depending on their personal outlook of the situation. But nevertheless, it's the best defense that Homer has.
