I don't know what that means
So could be wrong but 1 is A 2 is C and 3 is B what you had.
The purpose of setting a deadline for a goal is to establish accountability. For a personal goal, that accountability is a measure of success or failure in attaining that goal. For instance, if your goal is to obtain a bachelor's degree, a measure of accountability would be the deadline of achieving that in four years. Thus, achieving that degree in fifteen years could be seen as a failure. In a professional atmosphere, every goal and every project should have a deadline for completion to establish accountability and as a measure of efficiency and competency as well.
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
