Answer:b. storming
Step-by-step explanation:
The storming stage is a very challenging stage for a team but it is a stage that the team members need to overcome.
This is when conflict rises and there are clashes between group members due to diffrent personalities.
This may affect how the team works. This is the time when one starts to feel how frustrating the other person in a group may be because they start to see how they do things. This is the beginning of actual seeing the real person that you are going to work with. This is after an initial stage when everyone was nice to everyone but they now face the reality of their different characteristics and may not like each other at this point.
Ideas may also clash and even authority can be questioned at this stage.
At this stage the leader need to intervene and let members understand that it is ok to have different opinions but still find a way to embrace each others differences and keep working towards the target.
