To me, the most likely answer would be A.
I'd sat the answer is 'all of the above'. Because 'history of the relationship' is important - you won't greet a person you've just met the same way you'd great your best friend. "Context' is also important, because you won't speak the same way at a gala, or at a casual meeting with your friends. "Type of the conversation desired" is also relevant, because the way you greet someone will lead the course of your conversation.
The answer in B. escape from their enemies by jumping away
I would say the antagonist is Virginia Wolf or its a book you talking about?
