Given the list of options, for me, it's a no-brainer: B.
Look at all the other options closely, and notice the amount of toxicity they contain (except E, and I'm not clear on how it fundamentally differs from B). All in the service of earning one more grade point? It's silly.
Valedictorian is an award given to the student who most successfully exhibits the traits of gifted perfectionism, and all the baggage that entails. Depending on the size and/or quality of the school, making the top spot is a lot like an arms race.
Alternatively, you could bring a book from a real historian, slam it on the teacher's desk, and say, "This is how REAL historians do it." Because her teacher's preferred method of dealing with absolutes is absolutely incorrect when it comes to history. He should have gone into chemistry or mathematics instead.
I'm not saying it would be productive, but it would be satisfying. It would also communicate to your DD that you stand with her. Some of those other options (like A) have a potential communicate the opposite.
