Answer:
D. Norming
Step-by-step explanation:
Norming is the third stage in group formation. During this stage, members start to begin to form consensus and appreciate each other strengths. A majority of the conflicts have been resolved. Members agree on the group's leadership.
Because conflicts have been resolved, members socialize more freely. Members focus more on achieving the group objectives rather than personal interests. They collaborate more and offer constructive and helpful feedback to one another. Team performance increase due to the increased harmony.
