Answer:
All right, I won't flag you.
Step-by-step explanation:
I believe it would be Option C. My reasoning is simple: people are less inclined to help someone who is mean and/or makes them feel bad. They can understand your point, you could still have (albeit reduced) impact, you could say it however you want. But people don't want to be treated badly. That's why I picked C.
I hope this helps you. Where I am, it's about 7:45 AM at this moment, so good morning and have a great day!
