I choose A, I thought it was a Sufficente/ Necessity error confusion, but I can understand that the suttle part is when the argument give us an example of a recent research where flexibility works better than tighten groups if a common purpose is shared, but what if not? That means the sufficient condition is not meat and we lose the necessary condition, so we don't have an argument.
