Well i know it was a good story that's for sure and I would help you but............ you won learn to do anything that way and all you need to do is read those chapters and write what happened in a shorter form so i don't really see what you need help on, your just being lazy and don't wanna read which is horrible.
I believe it is A due to "The lady made detailed plans, engaged the caterer and the orchestra well in advance" isn't exactly connect well and be hard to understand so you'd put a comma between "caterer, and".
