The Administrators on the Geriatric Unit of University X Healthcare

The administrators on the geriatric unit of University X Healthcare System have a problem. The number of falls on the inpatient unit has increased over the past quarter by 25%. To address this issue, the administration has invited representatives from the medical group, nursing, physical therapy, occupational therapy, and social work to meet and develop an action plan. A representative from each of the invited disciplines has accepted. The first meeting is about to begin.
An example of a group is:

A) Three university students collecting data for a research project.
B) A committee designing staging for a play.
C) Parents playing with their children at a community playground.
D) Employees working at the drive through in a fast food restaurant.
