C. You don't have to add in past behaviors because one: there is no need and two: Writing down you goals, Develop an action plan, and rewarding your self is all steps of making a goal list. Hope it helps mate <3
I would say that an example that isn't a goal setting step is B. Reward Yourself because by rewarding yourself before you actually do something is going to make you unmotivated to do what actually needs to be done.
