Final answer:
The correct answer is D) Not all groups reach the 'performing' stage, which indicates that group dynamics or external influences may prevent a group from fully maturing to achieve efficient and independent functioning. Option D is correct.
Step-by-step explanation:
The question is concerned with Tuckman and Jensen's five stages of group development. The correct statement regarding these stages is D) Not all groups reach the 'performing' stage. This reflects the understanding that while groups aim to achieve efficient functioning, certain dynamics or external factors may prevent them from reaching the peak of their development.
In the forming stage, members get to know one another and begin to understand the group's task. Storming often involves competition and conflict as group members assert their ideas. By the norming stage, the group establishes agreements and consensus forms, which enhances group cohesion.
In the performing stage, the group is fully functional and works towards goal achievement. Finally, in the adjourning stage, the group dissolves after achieving its goals, or when it is no longer deemed necessary. Throughout the stages, groups may face challenges that can impede development to the next stage, particularly moving from norming to performing.
