The answer to this question is B. had planned
I don’t know if this is right but I think it is a metaphor if it isn’t I am sorry
I would say your answer is creating tension. the rest dont seem to work since refuting a counterclaim will make the argument weaker, but it will help the story, not bring it down. it obviously doesnt make the argument stonger, and the main purpose is for the audience to see both sides. so my answer would be creating tension. hope this helps
