All of the following could be another label for distributive bargaining except:

A) Adversarial bargaining
B) Hard bargaining
C) Traditional bargaining
D) Interest-based bargaining

Distributive bargaining is characterized by an adversarial or hard approach to negotiations, where each side is trying to maximize their share of a fixed pie. Traditional bargaining can also be a label for distributive bargaining, as it refers to the historical approach to negotiations that has focused on dividing a set amount of resources. Interest-based bargaining, on the other hand, is a different approach to negotiations that seeks to identify the underlying needs and interests of each party and find mutually beneficial solutions. Therefore, D is the correct answer, as it is the only option that is not a synonym of distributive bargaining.
