Which of the following statements represents a teamwork challenge?

The statement about differences in prioritizing tasks represents a teamwork challenge because it highlights a common issue that can arise within teams when members have varying opinions on what is most important or urgent. When team members prioritize tasks differently, it can lead to misunderstandings, miscommunications, and potential conflicts. This divergence can cause delays in project timelines and reduce overall team productivity.

In contrast, the other statements reflect positive aspects of teamwork. Members working well together indicates harmony and collaboration, sharing a common goal emphasizes the unity and direction of the team, and effective conflict resolution showcases the team's ability to handle disagreements constructively. These elements contribute to a successful team environment, while differing task priorities require careful management to ensure that all team members can align their efforts effectively.
