Which of the following is a stage of group development?

The correct stage of group development is storming, which is a well-recognized phase in Bruce Tuckman's model of group dynamics. In this stage, group members begin to express their individual thoughts and ideas more freely, leading to conflicts and disagreements as they attempt to assert their positions and find their roles within the group. This tension is a natural part of the development process, as it helps group members address differing perspectives and lays the groundwork for effective collaboration.

Storming is fundamental because it helps the group move beyond superficiality to deeper discussions, ultimately leading to better cohesion once the team resolves its conflicts. This stage is critical for growth, as the challenges faced often lead to stronger relationships and a more effective team dynamic in the long run.

Other options, such as establishing, collapsing, and evaluating, are not formally recognized stages in Tuckman's model of group development. Although establishing and evaluating processes may occur during group interactions, they do not define the cycle of group development in the same way as storming does. Collapsing suggests a negative outcome but does not represent a developmental phase within the group dynamics framework.
