The answer would be C. The clicking method hurts dogs’ ears. Remember that a counter argument in a way, contradicts what you say as a claim.
Let’s say your claim is “ The clicking method is a simple and effective method of training based on a positive reinforcement reward system.” You would then add a three - point thesis ( or reasons to support your claim) and throw in your counter claim. It would sound like “ Although the clicking method hurts dogs’ ears...” You then add something to the sentence to bring readers back to your side.
