I would not have chosen that one. I think what you've names is the process of oxidation/reduction. That is the loss or gain of electrons. I would go with b. For example,
Cl2 +2e ==> 2Cl^- is a half reaction for Cl2. The oxidation state of Cl in Cl2 is zero. IN Cl^- each Cl is -1 oxidation state. Maybe I've been doing it wrong all these years.
Actually I don't like any of the definitions but I think b comes the closest. Here is what I found on Wikipedia.
