The answer is most likely D and is what I would choose, as setting up rules as to what to do will force people to stay on topic and make progress on their assignment. (BUT THERE IS A CHANCE OF THIS BEING WRONG SO IF YOU FEEL IT IS WRONG PLEASE CHOOSE A INSTEAD A IT WOULD MEAN BY FINDING COMMON GROUND THEY WOULD BE ABLE TO DECIDE WHAT TO DO SO PRESS WHAT YOU FEEL IS MOST CORRECT) Very sorry if I'm wrong and good luck!
