Answer:
B. Choose roles
Explanation:
Choosing roles would be the best choice in order to avoid the problem stated, because certain people can be put to work on a certain section of the project (that they are suited for). That way, no one will feel as if they lack the skills to complete another part of the project.
Choosing an organizer wouldn't help much because they'd only be organizing the project itself, not the parts that people play within it. Identifying deadlines wouldn't help at all. It would cause stress if anything. Lastly, listening carefully also wouldn't help, because listening to so-and-so won't do anything to the problem at hand. You'd just be listening.
hope this helps!
