As meeting chair,you should:

A) expect conflict and deal with it forcefully.
B) let participants decide how the meeting will be run.
C) opt for more one-on-one than group meetings.
D) make ground rules explicit.

Making ground rules explicit is important to ensure that all participants understand the expectations for behavior and communication during the meeting. This can help prevent conflict and ensure that the meeting runs effectively. Expecting conflict and dealing with it forcefully may create a negative tone at the start of the meeting, while letting participants decide how the meeting will be run may lead to disorganization and lack of focus. Opting for more one-on-one meetings may not be feasible or efficient for all situations.
