Step-by-step explanation:
The correct answer is d. Task group.
A task group is created by an organization to accomplish a relatively narrow range of purposes within a stated or implied time horizon. Task groups are formed to address specific projects, tasks, or problem-solving activities, and disband once the objective is achieved.
