A Community Member Is Chairing the Meeting Where Several Persons

A community member is chairing the meeting where several persons were disagreeing for quite a while. The most appropriate approach for the chairperson is to

A) suggest that they table their discussions till the next meeting.
B) say, "I think you are acting rather unprofessionally, it would be good if you cool off a bit before we proceed."
C) say, "It is hard when we don't agree with one another, but for the good of all the members, let's try and get along."
D) adjourn the meeting and meet with them individually.
E) say, "Let us try and get to the bottom of the disagreement then we can attend to the other matters before us".
