A group has which of the following characteristics?

• A. Membership definable.
• B. Unity and interaction.
• C. Shared purpose.
• D. All of the above.

Answer: (D)

In group work, a group is defined by three interrelated qualities: membership that can be identified, ongoing unity and interaction among members, and a shared purpose that guides their work together. Membership being definable means you can specify who belongs and who doesn’t, rather than it being just a loose gathering. Unity and interaction show that members relate to one another, communicate, and influence each other as they participate. Shared purpose provides a common goal or objective that aligns their efforts. When all three are present, you have a true group rather than a casual crowd or disparate individuals. Therefore, all of the above best describes a group.
