How do you know which counterargument to address? A. I choose the weakest counterargument to make my argument look better. B. I select the strongest or the most popular counterargument. C. Actually, it is best never to mention counterarguments because they are a distraction. D. I use the first one that comes to mind.

B. Use the strongest and most popular counterargument, and then go on to explain why it is less valid / less important than your argument. You should always address the counterargument (don't just pretend it doesn't exists because it always does. This makes it clear you have considered both sides of the argument when forming an opinion, which makes it more difficult for people to disagree with you).
