Answer:
A. Ravens
Explanation:
I think this is because it's black and likes to be alone, that's why it's associated with death.
I believe that B. would be inappropriate in formal writing because its just kind of rude to say. I would re-word it as: "He dislikes being late" or something like that because "hate" is just a cruel and informal word to use.
Hope this helps!!! (:
