During which stage of team development do team members attempt to jockey for power, ask many questions and establish dubious goals? forming storming norming performing

I believe the answer is: Storming

During this stage, each members would start to make attempts to establish trust with one another, and determine which members had the power to call the shots in group's decisions.
During this time, several members may come up to fight for dominance and those who could win the support from other members would take the leadership position.
