C to model the concepts of the presentation
I believe the best answer would be D.
This is because the other answers don't really seem too encouraging. For example, the first one is basically saying she doesn't have any skill by saying "you might get lucky". The second one is just common sense that it's discouraging. The third one isn't encouraging either because it's saying that there's a chance she might mess up with the words "What's the worst that could happen?"
Hope this helps.
