Answer:
The correct answer is the option D: Adjourning.
Step-by-step explanation:
On one hand, the model of group development was first introduced by Bruce Tuckman in 1965 who stated that there are certain phases that a team must go throuw in order to grow, face up challenges and deliver results. Moreover, he established that there are four original stages of group development, and later added one more. Those stages are: Forming, Storming, Norming, Performing and Adjourning.
On the other hand, the stage called Adjourning is the phase where the team has broken up and every member involved takes a different path, as a result of completing the task for what the group was formed in the first place.
