Which of the following conflict styles assumes all parties must make concessions?

The correct choice is centered around the idea of compromise, which inherently involves all parties making concessions to reach an agreement. In a compromise situation, each individual or group identifies their needs and expectations and then negotiates to find a middle ground. This often means that while no party gets everything they want, they agree to give up certain aspects in order to achieve a mutually acceptable solution.

In contrast, collaboration focuses on finding a win-win scenario where all parties can achieve their goals without having to give anything up. Avoidance typically involves evading the conflict altogether, leading to no concessions or resolution. Competition, on the other hand, emphasizes winning over the other party, often resulting in one side achieving their goals at the expense of the other, without any significant concessions made by the winner. Thus, compromise uniquely embodies the requirement for both sides to adjust their positions to reach a resolution.
