Hey there. Sounds like an interesting story..
I would probably chose B as the best choice since it summarizes the main points of the story. A is the second best choice, but it only mentions the guitar. C and D both miss major parts of the story, only mentioning the clothes and shopping. Hope this helps you out. :D
So I normally use the word Climax but I'm assuming that climax and main action are the same thing. The main action is definitely (B) - Mary's husband tells her that he is leaving her, because that is what starts the suspense.
Please tell me if that isn't right, I think it is.
