I disagree with A. You picked A because you assigned +2 for O but the oxidation number for O is -2. N in HNO3 is +5.
So it would be C?
Yes.
Here is a web site that does a very good job of explaining so many different aspects of chemistry. I suggest you save this. It will come in handy when you need to look up something.
