The stages included in Tuckman's group development model are forming, storming, norming, performing, and later, a fifth stage called adjourning. This model outlines the typical phases that teams go through as they develop and grow together.

In the forming stage, group members come together and start to understand their roles and establish relationships. During the storming stage, conflicts may arise as individuals express their differing opinions and work towards determining how they will operate together. The norming stage is characterized by an emerging sense of cohesion and collaboration, as the group establishes norms and strengthens its relationships. Finally, in the performing stage, teams function at a high level of efficiency and effectiveness, fully utilizing their individual and collective strengths.

Choosing this answer accurately reflects the foundational understanding of how groups evolve over time, based on Tuckman's observations of group dynamics. The other answer choices represent different concepts unrelated to the stages of group development proposed by Tuckman.
