Final answer:
The stage in group development where members accept and understand one another, resolve differences, and develop team cohesion is known as the norming stage.
Step-by-step explanation:
In the stage where group members come to accept and understand one another, resolve differences and develop a sense of team cohesion, this stage of group development is known as d. Norming.
During the norming stage, groups establish a set of common standards and behaviors. This phase follows the storming stage, where conflicts and competition are at their peak and precedes the performing stage, where groups are functioning at a high level of efficiency and cooperation. In the norming stage, group members begin to smooth over their differences as they start to value and respect one another, allowing the team to become more united and to work more effectively towards their shared goals. It's in this stage that group cohesion forms, which is crucial for the team's success in the subsequent performing phase.
